MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200FSAAG1A DS200FSAAG1ABA Field Supply Amplifier Board supplies regulated current to DC motor field windings. This board accepts low-level analog commands from the main drive controller. You will find it converting these signals into a controlled DC output current. It ensures accurate field flux regulation for precise motor speed control.
Core Technical Specifications
The GE DS200FSAAG1A DS200FSAAG1ABA Field Supply Amplifier Board measures 32.0 cm in width and 24.0 cm in height. Its board depth equals 4.5 cm including heatsink and transformer heights. The total assembly weighs approximately 1.0 kilograms. A single high-current output channel provides continuous field supply current. Two SCR bridge modules perform the AC to DC conversion process.

Connectors and Terminals
The GE DS200FSAAG1A DS200FSAAG1ABA 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 leads. 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 DS200FSAAG1A DS200FSAAG1ABA 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 any fault condition.
Energy Storage and Thermal Management
This field supply board contains large filter capacitors on the DC output stage. These capacitors store approximately 12 joules of energy at full voltage. Therefore, the board retains hazardous energy after power removal. The GE DS200FSAAG1A DS200FSAAG1ABA 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.
