The 50-A version is used in the GL-T8500 transmitter; the 90-A version is used in the GLT8600 transmitter. The supplies provide power to other assemblies within the rack, including cooling fans. Refer to Table 3-1 Gold Line Power Supply Options for more information. Table 3-1 Gold Line Power Supply Options 3.2 item condition transformer 90 A power supply 60 Hz 6401.00019 90 A power supply 50 Hz 6401.00018 50 A power supply 60 Hz 6401.00020 50 A power supply 50 Hz 6401.00017 Physical Description The supply chassis must accommodate more than one type of equipment rack. Accordingly, the assembly may vary slightly for proper cooling and mounting requirements. Weight varies with supply configuration. Also refer to Table 2-1. Figure 3-1, Front View of Gold Line 50-A Power Supply shows the front of the power supply, and Figure 3-2, Top View of Gold Line 50A Power Supply shows a view of the power supply from the top. 3.2.1 Mounting Provisions The power supply is mounted in a standard 19-inch rack. Some rack cabinets do not have equipment access from the back; others do. The steel supply chassis has no top or sides. The protective front cover attaches to the front rail of the rack cabinet. The chassis is folded on the bottom to allow it to slide between the rack-cabinet floor and two floor-mounted bars. The chassis is held in place with two bolts that attach to the rack cabinet through the lower front edge of the chassis. The supply is mounted at the bottom of the equipment rack in all single-transmitter configurations. The supply requires little cabinet space. Refer to Figure 3-1, Front View of Gold Line 50-A Power Supply for detail. The front panel of five RUs (8.75 in) in height contains a circuit breaker and fuses. Figure 5-1, Gold Line 50-A Power Supply Front-Panel Controls and Indicators shows and describes their functions. Print Date: 12/17/96 Copyright © 1996 Glenayre Page: 3-1 Gold Line Power Supplies DESCRIPTION 3.3 Glenayre Document Number: 9110.00159 Issue 1, Rev. D: 02/01/96 Simplified Description Ac power flows to power transformer T1; circuit breaker CB1 provides protection against excess current. The rectified and filtered 25-volt output is supplied to other transmitter assemblies. The 25-volt output also goes, via fuse F1, to the 13.5-volt regulator board, which provides 13.5 volts for use by the transmitter.

The function and ratings of fuses are clearly labelled on the equipment. Note that the fuses are visible from the front panel. In most cases a blown fuse is obvious by visual inspection. Note their condition when troubleshooting the equipment. 5.2 Operating Instructions The power supply operates in an unattended manner during normal system operation. Use the circuit breaker and fuses when it is necesary to perform maintenance or troubleshooting. Set the circuit breaker to up position to turn on power supply. Set the circuit breaker to down position to turn off power supply.

D: 02/01/96 6.1 Gold Line Power Supplies THEORY OF OPERATION THEORY OF OPERATION Chassis Components Refer to Figure 6-1 and Figure 6-2. Ferroresonant transformer T1 and resonating capacitor C1 act as a reservoir to allow a constant voltage output despite changing load conditions as long as a constant voltage is applied to the input. It is electrically protected by circuit breaker CB1. There are taps on the primary of the power transformer to allow various ranges of input voltage. Output is rectified by CR1 and CR2, and filtered by C2, C3, and C4, and C5 to provide a filtered, stable dc output. Dc output for the PA is cabled directly from the filter capacitor assembly to terminals mounted on the side of the equipment rack. Dc for the exciter, receiver, controller, fans, and auxiliary equipment is routed through plug J1. 6.2 Voltage Regulator Assembly Refer to Figure 6-3. The 13.5-volt output of voltage regulator IC U1 is set by the values of R1 through R3. Associated components filter and protect the assembly from damage due to electrical transients.

D: 02/01/96 Gold Line Power Supplies CHECKOUT AND TROUBLESHOOTING CHECKOUT AND TROUBLESHOOTING 8.0.1 Test Equipment and Tools Required Common hand tools are required for assembly and disassembly. An RFI-immune voltmeter is required to measure dc voltages. 8.0.2 Precautions Follow all danger advisories in paragraph 9.1, as ac power is applied to equipment during some tests. Only qualified technicians should perform these service items. 8.0.3 Resonator Capacitor Check With main power applied, connect a dc meter across the supply dc output. Level should be 24-27 Vdc. . This check is complete. 8.0.4 Transformer Check With ac input power applied, connect an ac meter across the secondary winding of the transformer. Approximately twice supply voltage (50 Vac) should be present. This check is complete. 8.0.5 Diode Check With power off, disconnect each diode from the heat sink. Check with ohmmeter in diode-checking mode from each diode anode to the heat sink; normal dc conduction should be present from each one. This check is complete.

Disconnect ac power before removing any covers. DANGER The power transformer is heavy. Follow precautions for heavy lifting. 9.2 Test Equipment and Tools Required Common hand tools are required for assembly and disassembly. An RFI-immune voltmeter is required for voltage measurement. 9.3 Ac Voltage Change If the power supply or power transformer is replaced, the expected input voltage must be set before ac power is applied. Refer to the installation in Section 4. 9.4 Component Locations Regarding component locations in the 50A supply, see Figure 3-1, Figure 3-2, and Figure 7-1. Regarding component locations in the 90A supply, see Figure 3-3, Figure 3-4, and Figure 7-2. 9.5 Chassis Removal and Reinstallation Heed all danger references at the beginning of this section. Refer to Figure 9-1, Power Supply Removal and Reinstallation from/into rack throughout this procedure.The 90A power supply picture is similar except it has four capacitors instead of two.

Remove the front cover; it is held by several machine screws. 3. Remove two bolts in bottom-front of supply chassis. 4. Pull chassis out of rack enough to access electrical connections. 5. Disconnect wiring harness plug. 6. Remove dc cables from filter capacitor gridwork. 7. Disconnect 3-conductor power cable from rear-mounted TB1. 8. Remove supply from rack carefully. This procedure is complete. 9.5.2 Reinstalling Power Supply into Rack Installing the supply is done by performing the following steps: 1. Set the supply partially into rack. 2. Connect dc cables to capacitor gridwork. 3. Reconnect 3-conductor power cable to rear-mounted TB1. 4. Reconnect wiring harness plug. 5. Push supply into rack; be careful not to damage any wiring. 6. Secure supply with two bolts in bottom-front edge of chassis. 7. Secure front cover with machine screws. This procedure is complete. 9.6 Removing and Reinstalling the 13.5-Volt Regulator If it becomes necessary to replace the 13.5-volt regulator, perform the following procedures. Refer to Figure 9-2, 13.5-Volt Regulator Board Removal and Reinstallation throughout these procedures. It is assumed that the power supply chassis has been removed from the rack.
