Product Description
Product: DS200CDBAG1BDB – GE Mark V CDBA Contactor Driver Circuit Board
GE DS200CDBAG1BDB | Contactor Driver Board for Speedtronic Mark V Turbine Control & AC2000 Drives
DS200CDBAG1BDB is a GE CDBA Contactor Driver Board built for the legacy Speedtronic Mark V turbine control system and AC2000 medium voltage drive cabinets. This board provides regulated drive signals to high-power main circuit contactor coils. It delivers a high-voltage pulse for fast contactor pull-in, then switches to low holding voltage to reduce coil heat generation. When fault signals are triggered, it cuts coil power instantly for rapid safety trip protection. It works in tandem with DCFB power supply boards and other Mark V rack modules to manage main power switching for gas turbines, steam turbines and large variable frequency drives.
