IS220PSFDH1A Functional Description

The Flame Detector Power Supply GE IS220PSFDH1A is a critical component of the Mark VI turbine control system, designed to provide reliable power for flame detection in gas turbine operations. This robust power supply delivers 335V DC output (with 5% tolerance) capable of supporting up to eight flame detectors through its unique triple modular redundant (TMR) diode-ORed configuration, ensuring continuous operation even if two power supplies fail. The General electric IS220PSFDH1A Power Supply features a wide operating range of -30°C to 65°C with convection cooling and provides 1700V DC isolation for enhanced safety.

Key technical specifications include 28V DC input (26.6-29.4V range), 7mA current limit, and soft-start capability (550mA inrush current limit). The unit incorporates three diagnostic LEDs, over-voltage protection, and filtered input to minimize electromagnetic interference. The IS220PSFDH1A Phoenix Controls General Electric conformal PCB coating enhances durability while maintaining its functional A-rated revision status, representing a performance-focused upgrade within GE's Speedtronic control technology lineage.

Installation involves mounting above the TRPG terminal board with proper chassis grounding (FE). Electrical connections require: 1) 335V DC output to TRPG's J3/J4/J5 via 2x2 connector P2, and 2) 28V DC input through 1x3 connector P1 which features built-in soft-start functionality. The IS220PSFDH1A Power Supply 335 VDC compact design eliminates need for cooling fans while maintaining reliable operation.

As part of the advanced Mark VI series, the Power Supply 335 VDC GE IS220PSFDH1A represents significant improvements over previous Mark V systems, extending application capabilities to include wind turbine controls while maintaining GE's patented Speedtronic technology. Its robust design and fail-safe features make it essential for critical turbine protection systems in power generation applications.

SPEEDTRONIC™ Mark VI Turbine Control System – Advanced Power Generation Solution

The GE Mark VI system represents the pinnacle of turbine control technology, offering integrated protection, monitoring, and control for gas/steam turbines and generators. As GE's most advanced Speedtronic™ platform, it combines 30+ years of turbine expertise with modern digital control architecture. The system's core uses 13 or 21-slot VME racks with TMS320C32 DSP-processor I/O cards that filter and convert data to 32-bit floating-point format. Available in both simplex and Triple Modular Redundant (TMR) configurations, the TMR version employs three independent control modules with synchronized 40ms voting cycles via Software-Implemented Fault Tolerance (SIFT). Critical outputs use 2-out-of-3 relay voting or three-coil servos for valves, while diagnostics distinguish between sensor and internal faults. The system supports 9+ I/O racks, mixed redundancy sensors, and hot repairs during operation. With conformal-coated IPC-CC830 electronics and dual-port memory architecture, the Mark VI delivers unmatched reliability for power plants, featuring distributed control modules, IONet communication, and seamless integration of balance-of-plant systems.
