Description

The GE IS220PSFDH1A Flame Detector Power Supply Module is designed to deliver stable high-voltage output for up to eight flame detectors in Mark VIe turbine protection systems. Mounted above the TRPG terminal board, it draws 28 Vdc input from a JPDL power distribution board and outputs 335 Vdc at 5 mA. Its diode-ORed TMR configuration ensures full redundancy—each unit can independently power all detectors if others fail.
