1.0 INTRODUCTION

Your new Vector MAXX SST inverter is one in a series of the most advanced DC

to AC inverters available. With proper care and appropriate usage, it will

provide years of dependable service in your car, truck, RV or boat.

The MAXX SST supplies continuous power and peak watts, in the form of three

plug-in outlets ready to deliver 110/120VAC power whenever and wherever

you need it! This inverter has enough power to run most

household or electronic appliances. Added safety features include automatic

shutdown and a low battery alarm to prevent damage to your battery.

This Power Inverter is configured with the latest Soft Start Technology (SST).™

Before introduction of Soft-Start, high start-up currents from large inductive loads

could shut down the inverter. Soft Start improves inverter operation by:

1. Gradual voltage ramp-up during inverter start-up. This eliminates failed cold

starts under load.

2. Output that momentarily dips in voltage and quickly recovers to allow

large motorized loads to start. This eliminates almost all shutdowns from

momentary overloads.

3. This power inverter also incorporates a new cooling technology. The new

design cools the power transistors more efficiently, and combined with Soft

Start, dramatically increases reliability and the life of the product.

1.1 BASIC TOUR OF THE MAXX SST™ MODEL INVERTER

AC power is supplied via three standard North American grounded, plug-in

receptacles (U-ground) as shown in FIGURE 1 (#1). This allows the connection and

operation of most 110/120VAC powered electrical and electronic

appliances.

Other front panel items are:

One green LED (#2) that lights when the inverter is operating.

One combination over-temperature and overload LED (#3). If this lights, the

inverter will automatically shut down.

One on/off switch (#4) that shuts off the AC output and all inverter functions.

The on/off switch is also used to reset the inverter, after shut down, due to overload

or over-temperature condition.

FIGURE 2 shows the back panel DC connectors and fan locations. Note: The

fan only operates when the inverter’s load requires it to operate. It shuts off

when cooling is not required.

MAXX SST™ inverters are ideal for powering:

•TV/VCR combinations

•Refrigerator/freezers

•Lights

•Radio receivers/transceivers

•Heavy duty power tools & chargers

•Stereo systems

•Small microwave ovens

•Household appliances

•Computers and peripheral equipment

•Dry and/or wet-and-dry vacuums

•Sump pumps, motors and other electric-powered equipment

MAXX SST™ uses a 12VDC power source like those found in motor vehicles, or

it can be operated using multiple battery configurations with commercial battery

chargers or solar battery chargers. For most heavy-duty applications, a multiple

battery configuration and the use of deep-cycle batteries is required.

When using multiple batteries, inverters can be operated from one of the vehi-

cle 12 volt batteries, so there’s always one battery with adequate charge to

start an engine.

MAXX SST™ includes a high-surge capability. This is required to start heavy

loads, such as motors and other inductive devices.

1.3 APPLIANCE CAUTIONS

NEVER plug small appliances into the inverter outlets to directly recharge nick-

el-cadmium batteries. Always use the charger provided with that appliance.

NEVER plug in battery chargers for cordless power tools, if the charger carries a

warning that dangerous voltages are present at the battery terminals.

Some fluorescent lamps may not operate properly with this type of inverter. If the

bulb appears to be too bright, or fails to light, do not use the lamp with this inverter.

Some fans with synchronous motors may slightly increase in speed (RPM) when

powered by the inverter. This is not harmful to the fan or to the inverter.

Certain chargers for small nickel-cadmium batteries can be damaged if

plugged into the inverters.

DO NOT use inverters with the following two types of equipment.

1. Small, battery-operated appliances such as flashlights, cordless razors and

tooth brushes that can be plugged directly into an AC receptacle to

recharge.

2. Certain battery chargers for battery packs that are used in some cordless

hand-tools. Chargers for these tools have a warning label stating that

dangerous voltages are present at the battery terminals.

The majority of portable appliances do not have this problem. Most portable

appliances use separate transformers or chargers that plug into AC receptacles

to supply a low DC or AC voltage output to the appliance. If the appliance label

states that the charger or adapter produces a low DC or AC voltage output

(30 volts or less), there should be no problem powering that charger or adapter.

6

2.0 INVERTER APPLICATIONS

Aside from issues of supplying power to higher wattage appliances, inverters

must be supplied with a constant source of high current 12VDC from a bank of

batteries. At full watt load, the DC input requirements are up to 15 amps at

12VDC.

Read and comply with the following applications, and your inverter will give

you years of reliable service.

2.1 UNINTERRUPTIBLE POWER SUPPLY (UPS)

Inverters can be operated as uninterruptible power supplies that continuously

provide AC even if outside AC is interrupted. This function continuously

operates the inverter from a battery bank, simultaneously replacing the charge

to the battery bank with an AC-powered 12 volt battery charger. Charging can

also be by means of a solar charger system. (See FIGURE 3). The charger must

be selected to operate continuously in order to fully replace the charge on the

battery as the inverter operates. In this configuration, the battery "floats" on the

DC from the charger, not really supplying power or being charged. When out-

side AC fails, the inverter continues to power the appliances for the life of the

useful charge of the battery bank. When outside AC is restored, the batteries

are charged as the inverter continues to operate. Battery charging must be

sized to replace the average current supplied by the inverter plus a little more

current. Another requirement is that the battery charging rate cannot exceed

10% of the Ampere Hour (AH) rating of the battery bank, otherwise the life of

the batteries can be dramatically reduced through overcharging. Most modern

battery chargers automatically adjust the charging rate based on the state of

charge on the batteries they are charging. For this type of operation, use deep-

cycle batteries and avoid charging at too fast a rate.

Common unattended applications for the UPS (floating battery) include power-

ing: sump pumps, safety lighting, communications equipment, burglar alarm

systems and computer systems.

Figure 3 – Uninterruptible Power Supply

WARNING: Never connect the inverter’s AC output to an

AC distribution system.

3.0 THEORY OF OPERATION

MAXX SST™ inverters change 12VDC into 110/120VAC RMS, electrical power.

This is accomplished in two steps. (See FIGURE 4).

The first stage raises the 12VDC input to 145VDC. The advanced design

of the DC-to-DC first stage uses high-frequency conversion techniques

that replace bulky and heavy transformers found in older inverter technology. The

output stage changes the 145VDC to 110/120VAC. This solid-state circuitry

ensures excellent overload protection and the ability to operate reactive loads such

as those found in inductive motors. The inverter’s output stage uses multiple banks

of metal-oxide semiconductor field-effect transistors (MOSFETS). This stage functions

as a high-power bipolar switch, alternately applying opposite polarity to the AC out-

let HOT and NEUTRAL terminals.

Figure 4 Simplified Diagram

Some Models only include volt, Amp and over temp indicators.

The 110/120VAC output of the inverter is in the form of a modified sine wave

(MSW) as shown in FIGURE 5. This type of waveform has the same energy char-

acteristics as the sine wave of commercial electrical power. The modified sine

wave is superior to the 100% square wave output (not shown) produced by

most other DC-to-AC inverters on the market. A modified sine wave, as com-

pared to a square wave, is vital to the efficient and proper operation of certain

appliances such as computers, TVs, and certain electronic equipment.

NOTE: Because of wave-shape differences, using standard digital or analog

voltmeters may not correctly read the inverter output voltage. Unless a true RMS

voltmeter such as a "Fluke 87", "Fluke 8060A", "Beckman 4410" or "Triplet

4200" is used, the reading will be from 2 to 20 volts low.

4.0 OPERATION

NOTE: Ensure that the total continuous power consumption of all tools and/or

appliances connected to the inverter (and in use) does not exceed the inverter’s

continuous watts rating. Also ensure that the start-up wattage for inductive

loads does not exceed peak watts for more than a second.

CAUTION: Appliances such as microwave ovens will normal-

ly draw more than their rated current and could possibly overload

the inverter when operating simultaneously with other appliances.

For example: A 600 watt microwave oven draws approximately

940 watts.

4.1 POWER REQUIREMENTS:

Most electrical tools, appliances and audio/video equipment have labels that

show the unit’s power consumption in amps, watts, or both. To avoid inverter shut-

down and possible damage to the inverter, avoid exceeding the watt rating of

this unit. If the power consumption of the tool or device is rated in amps, multiply

the amps by 110/120 VAC to determine the wattage.

For instance, a power tool rated at 4 amps will draw 440 watts. The inverter

has built-in overload protection so that if you do exceed the watt continuous

duty limit, the inverter will automatically shut down. Once the excessive load is

removed, the inverter can be restarted and resume normal operation.

Note: To restart the inverter, turn it off, and on. The on/off switch is located

on the front panel of the inverter.

The inverter powers resistive loads the easiest; however, larger resistive loads,

such as electric stoves or heaters, could draw more wattage than the inverter

can deliver on a continuous basis.

The following chart shows the approximate amperage at 110/120VAC and the

corresponding wattage at 110/120VAC for various common tools

and appliances.

NOTE: APPLIANCE SPECIFICATIONS MAY VARY FROM BRAND TO

BRAND. THIS TABLE IS OFFERED ONLY AS A GUIDE TO APPROXIMATE

POWER RATINGS. CHECK APPLIANCE MANUALS OR PRODUCT LABELING

FOR ACTUAL RATINGS. TO USE THE MAXIMUM OUTPUT OF

CONTINUOUS WATTS, MAXX SST MUST BE CONNECTED TO A DC

POWER SUPPLY CAPABLE OF PROVIDING 1/10TH OF INVERTER’S

CONTINUOUS WATTAGE RATING.

A. Power Output

The inverter will operate most AC loads within its power rating. Some induction

motors used in refrigerators, freezers, pumps and other motor-operated equip-

ment, require very high surge currents to start them. The inverter may not be

able to start some of these motors even though their rated current draw is with-

in specifications for this power inverter.

If a motor refuses to start, observe the battery voltage using a DC voltmeter while

trying to start the motor. If the battery voltmeter drops below 11 volts while the

inverter is attempting to start the motor, this may be why the motor won’t start.

Make sure that the battery connections are tight and that the battery (or batteries)

is (are) fully-charged. If the connections are good and the battery is charged,

but the voltage still drops below 11 volts, you may need to use a larger battery

(or battery combination).

B. Input Voltage

The inverter

will operate from input voltages between 10.5 and 15.5VDC. If the

voltage drops below 10.6 volts, an audible low battery warning alarm will sound.

The inverter will shut down if the input voltage drops below 10.5VDC. This built-

in feature protects the battery from being completely discharged.

The inverter will also shut down if the input voltage exceeds 15.5 volts. This

protects the inverter against excessive input voltage. Although the inverter

has built-in protection against over voltage, it may still be damaged if the input

voltage exceeds 15.5 volts.

NOTE: Exceeding recommended voltage limits will void manufacturer’s warranty.

10

Inductive loads, such as TVs and stereos, require more current to operate than do

resistive loads with the same wattage rating. Induction motors, as well as some TVs,

may require two to six times their rated wattage to start up. Because the MAXX

SST™ inverters have a peak watt power rating, many such appliances and tools

may be safely operated. The equipment that needs the highest starting wattage are

pumps and compressors that start under load. This equipment can be safely test-

ed. If an overload is detected, the inverters will simply shut down until the over-

load situation is corrected. Use the front panel switch to turn OFF the inverter,

then ON, to reset the inverter.

CAUTION: NO USER-SERVICEABLE COMPONENTS INSIDE.

OPENING UNIT WILL VOID WARRANTY.

4.2 DETERMINING BATTERY SIZE:

To determine the minimum battery size that you will need to operate appliances

from MAXX SST™ Models, follow these steps:

1. Determine the wattage of each appliance and/or tool you will need to

simultaneously operate from the inverter. To do this, read the labels on the

equipment to be operated. Usually, power consumption is shown in watts. If

it is shown in amps, multiply by 110 to determine the wattage.

2. Estimate the number of hours the equipment will be in use between

battery recharges.

3. Determine the total watt-hours of energy use, the total running time and the

average power consumption.

To get an estimate of the current (in amps) that the battery must be capable of

delivering, divide the load consumption power (in watts) by (10). Keep in mind

that most appliances are not operating for long periods of time. For example,

a typical home-use coffee maker draws 500 watts during it’s brew time of 5

minutes, but it maintains the temperature of the pot at about 100 watts. Typical

use of a microwave is only for a few minutes, sometimes at low power. Some

exceptions to brief operating times are lamps, TVs and computers.

4.3 BATTERY OPERATING TIME

FIGURE 6 is a set of curves that show how appliance load in watts or in

amperes affects operating time. These curves are only estimates of operating

time, dependent upon:

• The condition of the batteries

• The state of charge on the batteries

• The amount of other DC appliances drawing current from the batteries

Three curves were developed for a battery of 50 Ampere Hours (AH) capacity,

and three for multiple batteries in parallel. The higher capacity curves are for

120 AH, 200AH and 400AH capacities. These large capacity batteries clear-

ly extend operating time at full load. To extend operating time in general,

reduce the heavy appliance load to a minimum. Remember, you are operating

on stored energy and probably under power loss conditions. All operating time

curves assume permanent installation with the correct DC input wire (See Specs

Page 18) and a full charge on the batteries.

11

Figure 6 – Battery

Operating Time

For example, as shown in FIGURE 6, using a 400 amp hour battery (batteries),

if the average power usage will be 1000 watts, the operating time will be

about 150 minutes. A larger capacity battery will deliver more operating time

between recharges.

NOTE: The manufacturer recommends conservative estimates when selecting a

battery. More amp hours will deliver a reserve capacity, and a larger

capacity battery will not be subject to deep discharges. Ideally, the

number of amp hours (AH) you expect to use should be less than 50%

of the battery’s rated capacity.

4.4 PROTECTIVE FEATURES

LOW BATTERY ALARM:

An audible alarm will sound when:

1. The 12 VDC power supply voltage drops down to 10.6 volts. This indicates that

the battery needs to be charged or there is an excessive voltage

drop between the battery power source and the inverter.

NOTE: It is normal for the alarm to sound when the inverter is being connected

to, or disconnected from, a 12VDC-power source. This does NOT

indicate a problem. However, if this alarm sounds continuously, discon-

tinue inverter operation and charge the battery before resuming operation.

If the voltage drops to 10.0VDC, the inverter will automatically shut

down.

If the low voltage alarm sounds when the battery is fully-charged, refer to the

troubleshooting table for possible causes and remedies. (Pages 19-20)

CIRCUIT PROTECTION: The inverter

has electronic circuit protection against

overload or short circuit conditions.

12

WARNING: If turning the front panel mounted switch OFF then

ON does not reset the inverter, DO NOT ATTEMPT TO OPEN THE

INVERTER. Opening the inverter, for any reason, will void the war-

ranty. The unit must be returned to Vector Manufacturing, Ltd. for test-

ing and repair by professional factory technicians.

5.0 INSTALLATION

MAXX SST™ inverters will provide you with various watts of continuous, electrical

power (See Models Specification Chart Page 18) when powered by a 12VDC

source such as is found in a vehicle or multiple battery configuration as shown in

FIGURE 7. This manual does not describe all of the possible types of battery,

battery charging, and battery isolation configurations.

5.1 INPUT POWER REQUIREMENTS:

To properly operate the inverter, the DC power source must provide between

10.5 and 15.5VDC and nominally at 150 Amps. This DC power source must

be a well-regulated DC power supply as typically found in vehicle and

deep-cycle marine batteries. The DC power source may also be two 12 volt

batteries connected in parallel. On larger applications the power source may

be several batteries connected in parallel as shown on FIGURE 7.

Figure 7 –Battery Wiring

NOTE: Vector®Manufacturing recommends that for typical heavy-duty uses,

a specified or equivalent main buss fuse (See Page 18) be added as

close as possible to the power source (battery) positive terminal. The

fuse amperage must be sized to allow simultaneous operation of all

the AC appliances to be powered, with delay characteristics that

allow for the momentary high start-up current requirements of inductive

loads. Use the recommended fuse block (fuse holder) and fuse, or an

electrical equivalent. For full rated output and motor start-up surge output,

ensure that the installation is configured to handle the full load. FIGURE 7

is also used as a guide when the cables are measured for installing the

inverter; available through Vector Technical Support toll-free at (866) 584-5504.

5.2 OPERATING ENVIRONMENT

WARNINGS: DO NOT locate inverters in an area, room or compartment

where explosive or flammable fumes might be present. Areas

such as: engine room, engine compartment, boat, and small,

unvented battery compartments.

13

In all marine applications, DO NOT install the inverter below or near the waterline,

and keep the inverter away from moisture and water.

Use ONLY non-corrosive marine fasteners and fittings for installation. Only con-

nect the inverter’s DC input to existing wiring (which must be approved for

marine use) rated specified gauge, cable and length. (See Page 18) For cable

lengths exceeding 6 feet from inverter to batteries, call Vector Manufacturing

for additional installation information. The cable, fuse holder, fuse (not sup-

plied) can be purchased at an electrical supply company. The fuse holder and

fuse are a specified amperage rating (See Page 18) fuse and appropriate fuse

holder. Call Vector®Technical Support (954) 584-4446 or toll-free (866) 584-

5504.

CAUTION: To avoid possible dangerous conditions, the inverters must be

located where:

1. The unit is kept dry.

2. Air temperature is between 30°F (-1°C) non-condensing, and 105 degrees F

(40°C).

3. At least three inches of clearance from other objects is maintained for cooling

airflow.

4. The unit is not exposed to direct heat, sunlight or to explosive or

flammable fumes.

5. The unit is as close to the DC power source as possible.

CAUTIONS: This device supplies 110/120VAC electrical power directly to the

appliances through three standard, North American U-ground

receptacles. NEVER try to use the inverter with any 12VDC-

power source that uses a positive ground. Most vehicles, boats

and aircraft use negative ground systems.

Never connect the ground wire from the inverter to the DC negative input.

• CHECK to ensure that the combined loads of the appliances being powered

by the inverter DO NOT continuously exceed the inverter’s watt rating.

• NEVER place items on or over the inverter during operation

MAXX SST™inverters generate heat during operation like any high power

device and must be placed where cooling air can circulate to the internal fan,

and heated air can be removed.

For optimum operation, the inverter should be placed or mounted on a flat

surface; ideally, a normally cool metal surface to help diffuse the heat that is

generated. Two specified cables (See Page 18) will be required (not supplied);

each should be a specified length (See Page 18) to allow for full power oper-

ation and to provide flexibility in positioning the inverter. For safety reasons,

keep small children away from the inverter at all times.

5.3 INSTALLATION SEQUENCE

To wire the inverter to a 12VDC power source, observe the following cautions,

and follow the installation sequence for Quick Operational Check and

Permanent Installation.

CAUTIONS: Ensure that DC connection polarity is correct. Reversed polarity

will blow a fuse and may cause permanent damage to the inverter.

The manufacturer’s warranty does NOT cover damage due to

reversed polarity. Review FIGURE 2, if necessary, to identify the

location of the DC terminals.

•Ring terminals to fit cable ends and stud terminals

•Hardware to connect two specified cables to the battery bank

•A specified single length of specific AWG cable multi-stranded,

flexible, insulated cable

•A specified amp low voltage fuse holder and fuse (slow blow type

or use a specified fuse or equivalent fuse holder

•Mounting screws, bolts and nuts for mounting the inverter and

fuse holder

•A drill for mounting the inverter and fuse holder

•Lead-tin solder, flux, propane torch and an igniter for the torch

•Wire stripper/cutter tool

•Battery connector for specified cable for battery connection

PRELIMINARY INSTALLATION NOTES:

The inverter has four slots in its mounting bracket that allow the unit to be fastened

against a bulkhead, floor, wall or other flat surface. Ideally, the mounting surface

should be cool to the touch. It is more electrically efficient to use longer AC wiring

than DC wiring, so install the inverter as close as possible to the 12VDC power source.

Vector inverters can be operated in any position, however, if it is to be mounted on

a wall, mount it horizontally so that indicators, switches, outlets and terminal blocks

on the front panel are visible and accessible.

1) If inverter is to be installed in a vehicle, Vector recommends that the inverter be

shock mounted to either the floor (in a clear, safe area) or on a secure flat surface.

2) Locate a convenient place to mount the inverter and fuse holder.

3) Perform a test routing of the proposed cable length, but don’t do any cutting at

this time. (FIGURE 7)

4) Be sure that the positive (+) and negative (-) cables to the battery DO NOT exceed 6 feet.

5) Using a specified AWG cable, reposition the inverter and fuse holder if necessary.

6) After you have practiced the above preliminary installation steps, proceed with

the “actual” inverter installation.

After you have selected an appropriate location for the inverter and fuse block,

proceed with the actual installation of the inverter.

Contact Vector®Manufacturing for any further installation information or

questions. You can purchase fuses, fuse holders, specific cable or cable

battery connectors from your local electrical supplier or call Vector Technical

Support toll-free (866) 584-5504.

This procedure is for using locally purchased supplies. Make

appropriate changes to procedure if Vector Cable Set is purchased.

5.5.2 PERMANENT INSTALLATION PROCEDURES

The cables between the power source and inverter should be as shown in

FIGURE 7 (Page 13). Remove terminal cover and terminal nuts before starting

permanent installation.

Inverter DC cables and fuse installation are as follows:

1. Using tools and hardware, mount the inverter to a flat surface.

2. Mount the fuse holder to its mounting surface using appropriate hardware.

Ensure that mounting hardware does not touch any fuse holder or fuse con-

tacts. Ensure that fuse is removed from its holder.

3. Measure the cable twice before cutting the cable.

4. Cut one cable length to connect the negative (–) battery terminal and the

inverter’s negative terminal, leaving a little slack in the cable.

5. Cut another cable to connect the positive (+) battery terminal to one side of

fuse holder, leaving a little slack.

6. Cut the final cable to connect the other side of fuse holder to the positive (+)

terminal on the inverter back panel.

7. Strip the insulation of the three cables to 1-inch (2.45 cm) .

8. Crimp or sweat-solder the copper strands to ring terminals. For safety, do

this in an open space because it may require the use of a propane torch.

16

9. Crimp or clamp on a heavy-duty, battery-connection terminal to the other

end of the negative (–) and positive (+) cable. Connect the negative (–) bat-

tery terminal cable to the negative (–) battery terminal connector.

10. Ensure the inverter power switch is in the off position (see FIGURE 1).

11.

Connect the ring terminal end of the negative (–) cable into the black stud marked

(–) on the inverter back panel and tighten the retaining nut.

12. Connect the battery connector to the negative (–) battery terminal.

13. Connect the ring terminal end of the positive (+) cable into the red stud

marked (+) on the inverter’s back panel (see FIGURE 2) and tighten the

retaining nut.

14. Connect the other end of the (+) positive cable to one terminal of the

heavy-duty fuse holder.

15. Connect the other conductor of the heavy-duty fuse holder to the positive (+)

battery terminal.

16. Connect an insulated wire (at least #12 AWG) between the chassis ground-

ing screw on the inverter’s case and a solid electrical ground to minimize

possible electrical noise generation in TVs and radios.

Do NOT connect this wire to the negative DC input terminal.

17. Ensure that all electrical connections are tight.

18. Ensure that the inverter’s on/of switch is OFF.

19. Insert the fuse into the fuse holder. (There may be some sparking.)

20. Turn “on” the inverter and apply a test load to the AC outlets.

21. Ensure the battery has an adequate charge. If voltage is low, the cables may

be too long or the gauge too light.

22. If steps 17 and 21 do not correct the problem, contact Vector Technical

Support Department toll-free (866) 584-5504, for professional direction.

8.0 TROUBLESHOOTING

8.1 COMMON PROBLEMS:

POWER TOOLS AND MICROWAVE OVENS WON’T START

Read the information panel on each power tool carefully to accurately determine

the tool’s input wattage. The wattage output is sufficient to operate most power

tools and microwave ovens, but remember, the power needed to start the power

tool may be as much as 2 to 6 times its continuous wattage requirements.

"BUZZING" SOUND IN AUDIO SYSTEMS AND/OR SNOW IN TVS

Inverters are shielded to minimize interference with TV signals. Ensure that the TV

antenna provides an adequate "snow free" signal and the antenna cable is high

quality and shielded without the inverter operating. The problem may not

be with the inverter. However, in some cases, some interference may be visible,

particularly with weak TV signals. Try the following corrective measures:

•Position the TV and antenna further away from the inverter, if it is the cause

of interference. Adjust the antenna, or use commercial cable hook-up (if possi-

ble) for best results

• Do not operate high-power appliances or tools when you are watching TV

• Make sure inverter's case is properly grounded as described in section 5.5.2

item 16

INVERTER SHUTS DOWN OR BATTERY FUSE OPENS

Inverter will continuously deliver rated watts (FIGURE 6) of AC power

continuously and will deliver rated peak watts ; after which, the inverter may

shut itself down, or the battery fuse will open, due to overload or excessive load

demand on start-up. Replace battery fuse, if opened. Allow the inverter to cool

for at least 15 minutes before attempting to start or run a high current draw

device. Reduce the load on the inverter to its maximum rated output power.
