Features:
- GE Speedtronic Mark VIe series power supply module for turbine control systems
- Provides regulated DC power to I/O and control modules within the Mark VIe rack
- Industrial-grade construction with diagnostic capabilities for reliable power generation operations
The IS220PSFDH1A provides essential power functions common to the entire control rack, and is a critical component of the turbine control path, directly affecting the proper, normal operation of the overall turbine generator system. One or two IS220PSFDH1A power supplies are required per rack depending on the desired redundancy level.
For applications requiring enhanced reliability in power generation, the IS220PSFDH1A incorporates diagnostic capabilities that continuously monitor module health. In addition to standard single supply operation, the redundant configuration performs automatic switchover. The dual power configuration of the IS220PSFDH1A executes failover using internal circuitry that continually monitors the health of both supplies, automatically transferring the load to the secondary supply if the primary becomes unstable.
The IS220PSFDH1A's robust construction ensures reliable operation in demanding power plant environments. Using industrial-grade components selected for continuous operation, the module maintains consistent performance over extended periods. The diagnostic features of the IS220PSFDH1A detect potential failures before they cause turbine trips, contributing to overall plant availability.
The IS220PSFDH1A GE Flame Detector Power Supply may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Flame Detection Power Supply: Converts 28 VDC input to a stable 335 VDC high-voltage output to power Geiger-Mueller flame detectors.
- Triple Module Redundancy (TMR) System: Typically configured with three PSFD modules, connected via diodes or diode-ORed connections through the J3, J4, and J5 interfaces on the TRPG (Emergency Trip Terminal Board).
- High-Reliability Monitoring: Ensures that even if two power modules fail, the remaining module can independently drive all eight flame detectors in the system, maintaining uninterrupted combustion monitoring.
- Hardware Setup: No onboard jumpers or hardware switches; all voltage regulation is handled automatically by internal circuitry.
- Software Programming: Configuration is performed using ControlST* software suites (such as ToolboxST). The system automatically monitors the output voltage, and ToolboxST will issue an alarm if the voltage deviates from the preset range.
- Status Monitoring: The front panel features three diagnostic LEDs:
P28 In (green): Input power is normal.
P335 Out (green): High-voltage output is normal.
- Current Lim (red): Output current exceeds the 7 mA limit (typically occurs during a short circuit).
- ControlST Integration: Firmware files are bundled into specific versions of General Electric's ControlST software suite.
- IONet Delivery: New firmware is pushed directly to the module over the local proprietary Ethernet network (IONet) from the central Mark VIe controller.
- System Component Sync: Upgrading the hardware requires matching the firmware baseline assigned to your primary turbine controller configuration.
