Description
Product Introduction
This GE F31X111PSHALGI is a high-capacity, wide-input power supply board with configurable output options for GE’s excitation and power conversion control platforms. The “L” suffix indicates wide input range capability, and the “G1” suffix denotes the specific output configuration and revision. This board combines universal input voltage compatibility with flexible output configuration, making it ideal for diverse global installations and multi-platform applications.
The board accepts a wide input voltage range (85–264 VAC or 100–300 VDC) and provides multiple regulated DC outputs that can be configured to match various system requirements. It is designed for critical power generation and industrial applications where both input voltage flexibility and output configuration adaptability are required.

Key Selling Points & Differentiators
- Wide Input + Configurable Outputs: The only board in the series that combines universal input voltage with flexible output configuration. Simplifies global inventory management for OEMs and multi-site facilities.
- High Current Capacity: Provides up to 10 A on configurable outputs—supports demanding configurations with multiple control and communication modules.
- Comprehensive Protection: Overcurrent, short-circuit, thermal, overvoltage, and input surge protection. Robust front-end handles voltage transients and brownouts.
- Quantified Testing Protocol: We test the board at both voltage extremes (85 VAC and 264 VAC) with full load. We verify output voltage accuracy, ripple, and protection circuit operation for each configuration option.
- Warranty & Support: 2-year functional warranty. We provide configuration assistance and global installation guidance.
Frequently Asked Questions (FAQ)
Q1: What is the difference between the PSHALG1 and the PSHALGI? (Note: Assuming comparison to PSHALG1 and PSHALGI variants)
A: The PSHALG1 combines the wide input range of the L variant with the configurable output capability of the J variant. This is a unique combination that is not available on other boards in the series. It is designed for applications requiring both universal input voltage and output configuration flexibility.
Q2: What are the configuration options for this board?
A: The board can be configured for various output voltage and current combinations through jumpers and component selection. Common configurations include +5 V up to 10 A, +24 V up to 5 A, and ±15 V up to 2 A. We can provide the specific configuration options available for your requirements.
Q3: Can this board be used to replace a fixed-output power supply?
A: Yes, the board can be configured to match the output requirements of most fixed-output power supplies in the F31X series. This simplifies spare parts management by allowing a single board type to support multiple system configurations.
Q4: Does the wide input range affect the output configuration capabilities?
A: No, the wide input range is independent of the output configuration. The board can be configured for various outputs across the full input range. The wide input design does not limit the output flexibility.
Q5: Is the PSHALG1 compatible with the same systems as the PSHAEG1?
A: Yes, the board is mechanically and electrically compatible with the same F31X series backplane and systems. The configurable design allows it to replace many fixed-output boards in various applications.
Q6: Does this board have battery backup?
A: No, this specific variant does not include battery backup. It is a power supply only. If your system requires parameter retention during power loss, you would need a separate memory backup board.
Q7: What is the ripple specification?
A: The ripple is less than 50 mV peak-to-peak on the main outputs at full load. The ±15 V outputs typically have lower ripple (<30 mV). Actual ripple depends on the output configuration. We verify ripple during QC for each configuration.
Q8: What is the lifecycle status of the PSHALG1?
A: This is one of the rarest boards in the F31X series. GE produced it in very limited quantities for special projects requiring both universal input and configurable outputs. We have an extremely small batch of new surplus units. Used pulls are practically non-existent. If your application requires the combination of wide input voltage and configurable outputs, we strongly recommend securing a spare. Our new surplus units are fully tested and guaranteed. We do not expect to source more of this variant.
