Description

Product Introduction

This GE F31X111PSHATG1 is a ruggedized high-capacity power supply board with an extended operating temperature range for GE’s excitation and power conversion control platforms. The “T” suffix indicates this board is designed for harsh environments, with a wider operating temperature range and additional protection against vibration, humidity, and contaminants.

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. It is designed to operate reliably in ambient temperatures from -25 °C to +70 °C, making it suitable for outdoor installations, unheated enclosures, and other harsh environments where standard power boards would fail. The ruggedized design includes conformal coating, enhanced thermal management, and robust protection circuitry.

Key Technical Specifications

Key Selling Points & Differentiators

• Extended Temperature Range: Operates from -25 °C to +70 °C—significantly wider than standard boards (0 °C to +55 °C). Suitable for outdoor, unheated, or high-temperature environments.
• Ruggedized Construction: Conformal coating protects against moisture, dust, and chemicals. Designed to withstand vibration and shock in harsh industrial settings.
• High Current Capacity: Provides up to 10 A on the +5 V logic supply—supports demanding configurations even in extreme conditions.
• Quantified Testing Protocol: We test the board at -25 °C and +70 °C with full load. Thermal cycling and vibration testing are performed to verify ruggedized performance.
• Warranty & Support: 2-year functional warranty. We provide installation guidance for harsh environment applications.

Frequently Asked Questions (FAQ)

Q1: What is the difference between the PSHATG1 and the standard PSHAEG1?

A: The PSHAEG1 is the standard power supply with a 0 °C to +55 °C operating range. The PSHATG1 is the extended-temperature version with a -25 °C to +70 °C operating range. The PSHATG1 also includes conformal coating and additional ruggedization for harsh environments.

Q2: What is conformal coating and why is it important?

A: Conformal coating is a thin protective layer applied to the PCB that protects against moisture, dust, chemicals, and temperature extremes. In harsh environments, conformal coating prevents corrosion and electrical leakage that can cause premature failure. The PSHATG1 includes this protection.

Q3: Can the PSHATG1 operate in both very cold and very hot environments?

A: Yes, the board is rated for -25 °C to +70 °C ambient. This covers most outdoor and unheated industrial applications. At temperatures below -25 °C, the board may not start reliably. At temperatures above +70 °C, the board will protect itself by reducing output or shutting down.

Q4: Does the extended temperature range affect the output current capacity?

A: At temperatures above 55 °C, the board may derate slightly to protect components. At 70 °C, the +5 V output current is derated to approximately 8 A (from 10 A). At cold temperatures (-25 °C), the board delivers full current once warmed up. We provide a derating curve in the documentation.

Q5: Is the PSHATG1 more expensive than the standard board?

A: Yes, the extended-temperature and ruggedized construction adds cost. However, in harsh environments, the PSHATG1 will have significantly longer service life than a standard board, making it a better long-term investment.

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: Does the PSHATG1 have the same protection features as the standard board?

A: Yes, the board has the same overcurrent, short-circuit, thermal, and overvoltage protection features. The thermal protection is calibrated for the wider temperature range to ensure reliable operation at temperature extremes.

Q8: What is the lifecycle status of the PSHATG1?

A: This board is very rare. GE produced the PSHATG1 in limited quantities for harsh environment applications such as outdoor power plants, mining, and oil/gas installations. We have a small batch of new surplus units. If your application requires extended temperature operation, we recommend securing a spare. Our new surplus units are fully tested and guaranteed. We do not expect to source more of this variant.
