PRODUCT INFORMATION
Product Overview
The General Electric DS200DCFBG1B is a Mark V power supply board. This board delivers control-level operating power and enclosure fan power across supported drive systems. Compatible turbine drive platforms include AC2000, CB2000, DC2000, FC2000, ME2000, and EX2000 systems. The EX2000 excitation system utilizes this board differently from other listed drive architectures.
The board interfaces with SDCC and LDCC control cards to communicate motor voltage feedback signals. An internal voltage-controlled oscillator converts measured input voltages into frequency signals sent over connector 1PL. DIP switch SW6 provides active scaling and modification for motor voltage feedback. Onboard amplifier circuits further process these signals for the main control cards.
