The DS200DCFBG1BNC is a power supply board manufactured for General Electric’s Mark V series of replacement and optional boards. The DS200DCFBG1BNC circuit board is part of the Speedtronic Mark V control system. System control level power, as well as the enclosure fan, is provided electricity by this card. Compatible with a number of GE brand exciters and drives, this card can be installed in a variety of systems. Drives from the FC2000, AC2000, DC2000, ME2000, and CB2000 series can use this board. Voltages fed to the board can safely rate from 38 to 115 VAC.

DS200DCFBG1BNC includes five circuits around the board. These include a driver circuit, the control level supply circuit, a motor field power circuit, and both an AC and a DC monitoring circuit. To ensure the circuits are not disrupted, three of the fuses on board are protected. Should any fuses need attention, the integrated LED and neon indicators will alert the user. Monitoring voltage levels is important and can be done using one of the five test points on the card. User configurability is possible using the twelve jumpers and seven DIP switches.
