GE IS2020RKPSG2A RKPS VME Rack Power Supply Module
GE IS2020RKPSG2A (RKPS) is a high-capacity VME rack power supply module for GE Speedtronic Mark VI turbine control system. It accepts 125VDC input and converts it into multiple regulated DC voltages to supply power to VME backplane, CPU boards, I/O and communication cards inside the control rack. It is mounted on the right side of the VME chassis with dedicated wiring harnesses.
This power module delivers total 400W output, supplying +5V, ±12V, ±15V and ±28VDC, and it supports optional 335VDC output for flame detector circuits. It integrates overvoltage, overcurrent, short-circuit and thermal protection. It is discontinued legacy hardware, available as surplus or refurbished spare parts for existing Mark VI turbine control cabinet maintenance and retrofit.
