The General Electric IS220PSFDH1A Power Supply supports EX2100 and Mark VI turbine control systems with stable 335 VDC output for flame detection. This module powers up to eight detectors through a TMR diode‑ORed configuration that maintains continuous operation even during multiple supply failures. Its rugged design ensures reliable performance in demanding turbine environments.
Functional Design
The GE IS220PSFDH1A operates on a 28 VDC input range of 26.6–29.4 V and delivers a regulated 335 VDC output with a 5% tolerance. The unit includes soft‑start capability that limits inrush current to 550 mA and incorporates a 7 mA current limit for stable operation. Its 1700 VDC isolation improves system safety during high‑energy events.
Three diagnostic LEDs provide clear status visibility, while filtered input circuitry reduces electromagnetic interference. The conformal‑coated PCB enhances durability in harsh industrial environments and maintains the module’s A‑rated revision performance. The IS220PSFDH1A mounts above the TRPG terminal board and connects through P1 and P2 connectors for straightforward installation.
