MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200FECBG1A DS200FECBG1AAA Field Exciter Board controls the field current for DC motors. This board receives low-level analog commands from the main drive controller. You will find it generating a controlled DC output for motor field windings. It ensures precise field flux regulation for optimal motor torque and speed.
Core Technical Specifications
The GE DS200FECBG1A DS200FECBG1AAA Field Exciter Board measures 30.0 cm in width and 22.0 cm in height. Its board depth equals 4.0 cm including heatsink and transformer heights. The total assembly weighs approximately 0.85 kilograms. A single regulated output channel delivers continuous field excitation current. Two SCR power devices perform the AC to DC conversion process.

Connectors and Terminals
The GE DS200FECBG1A DS200FECBG1AAA Field Exciter 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 analog control signal and status feedback. Moreover, the board includes a 3-position jumper for input type selection.
Protection and Monitoring Features
This exciter board includes fast-acting fuses on both AC input lines. The board also monitors output current continuously for overload detection. Furthermore, the GE DS200FECBG1A DS200FECBG1AAA Field Exciter Board integrates a heatsink temperature sensor. A red LED illuminates during an overcurrent or overtemperature fault condition. A green LED confirms proper AC input and DC logic power presence. The board automatically disables the output during any fault condition.
Energy Storage and Thermal Management
This field exciter board contains filter capacitors on the DC output stage. These capacitors store approximately 8 joules of energy at full voltage. Therefore, the board retains hazardous energy briefly after power removal. The GE DS200FECBG1A DS200FECBG1AAA Field Exciter Board requires forced-air cooling for continuous operation. Wait 3 minutes after disconnecting AC power before touching any terminal. Do not operate the exciter without the proper heatsink attached. Replace the board if any capacitor shows bulging or leakage signs.
