MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200FSAAG2A DS200FSAAG2ABA Field Supply Amplifier Board provides regulated current to DC motor fields. This board receives low-level control signals from the main drive processor. You will find it converting these signals into high-current DC output. It ensures precise field flux control for DC motor speed regulation.
Core Technical Specifications
The GE DS200FSAAG2A DS200FSAAG2ABA Field Supply Amplifier Board measures 32.0 cm in width and 24.0 cm in height. Its board depth equals 5.0 cm including heatsink and transformer heights. The total assembly weighs approximately 1.1 kilograms. A single high-current output channel delivers continuous field supply current. Two SCR bridge modules perform the AC to DC conversion process.

Connectors and Terminals
The GE DS200FSAAG2A DS200FSAAG2ABA Field Supply Amplifier Board uses heavy-duty screw terminals for power connections. Two terminals accept 240 VAC input from the isolation transformer. Two terminals connect directly to the DC motor field winding. A 9-pin D-sub connector carries the control signal and status feedback. Moreover, the board includes a 3-position jumper for input type selection.
Protection and Monitoring Features
This amplifier board includes fast-acting fuses on both AC input lines. The board also monitors output current continuously for overload conditions. Furthermore, the GE DS200FSAAG2A DS200FSAAG2ABA Field Supply Amplifier Board integrates a heatsink temperature sensor. A red LED illuminates during an overcurrent or overtemperature fault. A green LED confirms proper AC input and DC logic power. The board automatically shuts down the output during fault conditions.
Energy Storage and Thermal Management
This field supply board contains large filter capacitors on the DC output stage. These capacitors store approximately 15 joules of energy at full voltage. Therefore, the board retains hazardous energy after power removal. The GE DS200FSAAG2A DS200FSAAG2ABA Field Supply Amplifier Board requires forced-air cooling for continuous operation. Wait 5 minutes after disconnecting AC power before touching terminals. Do not operate the amplifier without the proper heatsink attached. Replace the board if any capacitor shows bulging or leakage signs.
