Frequently Asked Questions

What is the key difference between 531X111PSHAPG2 and previous revisions?

This G2 version has specific relay and jumper configurations. The G3 version (PSHARG3) moves MOVs off-board. Verify your system requirements before ordering.

How do I verify the board works before installation?

Check continuity on relay contacts. Measure output voltages at test points with a multimeter. Confirm jumper settings match your drive manual.

Can this board handle 460VAC input?

Yes, but external MOVs must be rated for your line voltage. The board itself accepts standard AC inputs through the transformer.

What should I check if the FAULT relay stays active?

Inspect external MOVs for shorts. Verify field wiring insulation. Test the pulse transformer secondary for open circuits.

Is this board compatible with non-GE drives?

It is designed for GE 531X systems. Some third-party exciters may accept it – check voltage and relay logic compatibility first.

What is the typical lead time for this board?

In-stock items ship within 24-28 hours. Express courier delivery takes 2-5 business days worldwide.

Do you offer technical support for installation?

Yes. Our team can assist with wiring and configuration. Contact us via email or WhatsApp for guidance.

Selection Guide

• Confirm your drive model – 531X series compatible.
• Check your required DC outputs – 5V, 15V, 24V available.
• Verify relay logic (normally open/closed) matches your system.
• Order external MOVs separately for G3-compatible setups.
• Keep a spare to avoid extended downtime.
