Overview Manuals Specifications Application Configuration and Programming Firmware Updates Work

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).

  • Manufacturer General Electric/span>
  • Model IS220PSFDH1A
  • Condition New Original ready stock
  • Product Family IS220PSFDH1AA,IS220PSFDH1AG,IS220PSFDH1AIO
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • 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.
Description
The IS220PSFDH1A is a Flame Detector Power Supply manufactured by General Electric as part of the Mark VI Series used in gas turbine control systems. The primary gas turbine trip protection (TRPG) terminal board is normally mounted above the IS220PSFDH1A Flame Detector Power Supply (PSFD). A power distribution board provides 28 V dc as the source power (JPDL). 335 V dc, 5 mA is the output's rated rating. Up to eight flame detectors can be powered by three power supplies linked in a diode ORed, TMR arrangement to the TRPG's J3, J4, and J5. Should the other two power supplies fail, each supply has enough power to operate all eight flame detectors.

The IS220PSFDH1A is specifically designed to provide reliable and stable power to flame detection systems in industrial gas turbine applications, addressing the critical need for continuous flame monitoring and trip protection in power generation environments. It ensures that flame detectors receive consistent power, thereby preventing false trips and maintaining operational safety.

The IS220PSFDH1A is widely applied in power generation plants, oil and gas facilities, and other industrial settings where gas turbines are utilized for energy production. Its robust design supports the demanding requirements of these environments, ensuring high availability and reliability.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the difference between the IS200TRPGH2B and the IS200TRPGH2A?
The IS220PSFDH1A represents a later revision of the same base module, typically including firmware updates, component improvements, or expanded functionality. The
How to identify a reliable supplier for the IS220PSFDH1A?
A reliable supplier should provide traceable GE certification, verify the specific revision level, and demonstrate knowledge of Mark VI control systems. They must offer testing documentation and warranty coverage. Look for suppliers with power industry experience and technical support capabilities. Avoid suppliers who cannot verify the module's functionality or lack understanding of turbine control applications. Request photographs of the actual board and inquire about their testing procedures before purchase.
What certifications are required when exporting the IS220PSFDH1A to the United States?
The IS220PSFDH1A is a replacement part, so US import requires standard customs documentation including country of origin, product value declaration, and HTS classification. No specific UL or FCC certifications are typically required for this type of industrial control module. Importers should verify applicable tariffs and consult customs brokers for current regulations. For installations requiring hazardous area approvals, additional certifications may be needed depending on the specific location.
Why do turbine control modules fail while the IS220PSFDH1A survives?
Standard modules fail from thermal stress, power supply fluctuations, component aging, and environmental contamination. The IS220PSFDH1A survives with industrial-grade components rated for continuous operation in high-temperature environments, robust power supply filtering that rejects electrical noise, and conformal coating that protects against humidity and contamination. Its built-in diagnostic capabilities detect potential failures before they cause turbine trips, allowing preventive maintenance before catastrophic failure occurs.
