Description

Product Introduction

This GE F31X111PSHALG1 is a high-capacity power supply board with an extended input voltage range for GE’s excitation and power conversion control platforms. The “L” suffix indicates the board supports a wide input voltage range (85–264 VAC), making it suitable for international applications where input power varies by region or is not well-regulated. This board is ideal for global OEMs and installations in regions with unstable power quality.

The board provides multiple regulated DC outputs, including high-current +5 V for logic, +24 V for field devices, and ±15 V for analog circuits. The wide-input front-end automatically adapts to different voltages without jumpers or transformer changes, simplifying installation and reducing the risk of incorrect voltage selection.

Key Technical Specifications

Key Selling Points & Differentiators

• Wide Input Voltage Range: Accepts 85–264 VAC or 100–300 VDC. No jumpers or transformer changes required for different regional power standards. Simplifies global installations.
• High Current Capacity: Provides up to 10 A on the +5 V logic supply—supports demanding configurations with multiple control and communication modules.
• Robust Input Protection: Handles voltage transients and brownouts with a robust front-end design, including MOV and TVS protection. Suitable for regions with unstable power quality.
• Quantified Testing Protocol: We test the board at 85 VAC and 264 VAC input with full load on all outputs. Ripple is verified, and protection circuits are tested.
• Warranty & Support: 2-year functional warranty. We provide global installation guidance and a power budget calculator.

Frequently Asked Questions (FAQ)

Q1: What is the difference between the PSHALG1 and the standard PSHAEG1?

A: The PSHAEG1 has a fixed input range (120/240 VAC with a jumper). The PSHALG1 has a wide-range input (85–264 VAC, no jumper required). The power outputs are similar on both boards. The L variant is designed for international applications where input voltage varies by region.

Q2: What is the efficiency of the wide-input power supply?

A: The PSHALG1 has an efficiency of approximately 80-82% at full load, which is slightly lower than fixed-input versions due to the wide-range front-end design. The board dissipates about 5-8% more heat, but the thermal design handles this without derating at 55 °C ambient.

Q3: Does the wide input range mean I can connect it to any voltage without setting jumpers?

A: Yes, the board automatically detects and adapts to the input voltage. There are no jumpers or switches to set. This simplifies global installations and reduces the risk of incorrect voltage selection. The board accepts 85–264 VAC or 100–300 VDC.

Q4: Can I connect the board to 277 VAC or 380 VAC?

A: No. The maximum AC input is 264 VAC. Do not connect to 277 VAC or higher. For 380/400/480 VAC applications, you need an external step-down transformer. The board is designed for 120/208/230/240 VAC nominal systems.

Q5: Is the PSHALG1 more susceptible to voltage surges due to the wide input range?

A: No, the wide-input design includes robust input protection—an MOV and TVS to handle surges up to 2,500 V. This is actually better protection than some fixed-input versions. The front-end is designed to withstand industrial power quality issues.

Q6: Does this board have battery backup?

A: 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 output ripple specification?

A: The ripple is less than 50 mV peak-to-peak on the +5 V output at full load. The ±15 V outputs have ripple less than 30 mV. We verify ripple during QC across the full input range.

Q8: What is the lifecycle status of the PSHALG1?

A: This board is rare. GE produced the PSHALG1 in limited quantities for global OEMs and international projects. We have a small batch of new surplus units. Used pulls are very uncommon. If your system operates in multiple regions or has unstable power, this is the ideal power board. We recommend securing a spare. Our new surplus units are fully tested and guaranteed. We do not expect to source more of this variant.
