Battery Charger BAC25A Lightweight – only 10 kg / 22 Ibs Instrument max power – up to 2,7 kW Voltage range: 10-300 V DC Current range up to 25 A DC Measurement resolution – current 0,1 A, voltage 0,1 V Two charging modes available: IU - constant current + constant voltage, UU - constant voltage + constant voltage, with current limit Adjustable alarm and shutdown parameters for preventing excessive charge Powerful and Portable Battery Charger Description Following a power outage, various power engineering objects such as power plants should be kept operating on batteries. It is necessary batteries to be charged in order to compensate its energy loss and keep their voltage within the predefined limits. Battery charger BAC25A is a portable battery charger used for charging primarily Lead-Acid and Ni-Cd batteries. BAC25A is intended to support the main charger in order to charge battery much faster or to quickly recharge a battery following a discharge Mains Voltage (V AC) B-B025CN-307-EN 2017-02-27 230/115 test. Using two charging modes it provides the possibility of maintaining and recharging the batteries either with a constant current or a constant voltage. The output voltages are selectable in the range of 10 V to 300 V DC. This device generates current up to 25 A. In addition, it is equipped with thermal, overcurrent, and over-voltage or under voltage protection. Provided display enables users to read all relevant information during a charging process and to adjust the charging current, charging time, etc. Boost voltage (V DC) Float voltage (V DC) Voltage (V DC) Current (A DC) Lead-Acid Ni-Cd Lead-Acid Ni-Cd 12 Up to 25 14 15 13 14 24 Up to 25 29 30 27 28 48 Up to 25 57 60 54 56 60 Up to 25 72 75 68 70 133/145 140/150 125/135 130/140 263/290 275/300 148/270 250/280 110/120 220/240 Up to 20 (230 V) Up to 10 (115 V) Up to 10 (230 V) Up to 5 (115 V) 1 Benefits and Features 1.

Status indicating LED diodes 4. PT100 probe connector temperature measurement. 5. USB PC Interface. 6. Overvoltage alarm terminal - used for triggering external alarm. 7. Undervoltage alarm terminal triggering external alarm. 8. Current and voltage sense terminals connecting the current and voltage sense cables. for - ambient used for Application example Typical application is charging batteries that serve as a backup power supply in: Power plants Generator excitation systems Substations Protection and control systems UPS battery strings B-B025CN-307-EN 2017-02-27 The BAC25A instrument is connected to a test battery using the current cables. The voltage sense cables may be used optionally. Next step is to set the current and the voltage alarm levels. After starting the charging process BAC25A keeps the current or voltage level constant depending on the selected charging mode. When applying the IU charging mode the battery is charged with a constant current. The voltage increases to a level close to the final voltage (boost voltage), the device switches to a constant voltage (float voltage) mode and the current begins to decrease. Cut off occurs when a predetermined minimum current value, which indicates a full charge, has been reached. When opting for the UU charging mode the battery will be charged under a constant voltage. If the battery current becomes larger than the defined current limit, the charger will switch into a constant current mode and continue charging with constant current that is equal to specified current limit. Otherwise, the charger keeps charging under the selected constant voltage, the current will decrease over time until it reaches a predetermined minimum value. At this point of time the charger will switch to a float charge stage and decrease to a selected float voltage. 2 Technical Data Mains Power Supply Dimensions and Weight Connection according to IEC/EN60320-1; Dimensions: C320 (D x W x H) without handle: Voltage 90 V – 264 V AC, 50 / 60 Hz, 407 mm x 198 mm x 275 mm single-phase 16 in x 7.8 in x 10.8 in Power consumption: up to 3 300 VA Weight: 10 kg / 22 lbs.
