GE DS200DCFBG1BJB power supply and feedback board, for GE Speedtronic Mark V, EX2000 excitation and drive systems, critical turbine control spare part.

Product Overview

GE DS200DCFBG1BJB is a multi-functional power supply and signal feedback board for GE Speedtronic Mark V turbine control platform. It provides multiple regulated DC power outputs for rack controllers, I/O modules and cabinet cooling fans. Meanwhile, it samples armature voltage, field current and AC line signals, converts analog feedback into frequency signals and transmits them to SDCC / LDCC control boards for closed-loop drive and excitation regulation. It is compatible with EX2000, DC2000, AC2000 and other GE drive series. With conformal coated PCB, it can withstand vibration and electromagnetic interference in power plant cabinets, widely stocked as legacy system maintenance spare part.

Key Features

• Multi-channel DC power output: +5VDC, ±24VDC for control hardware
