4. Product Introduction

The ABB APOW-02C is the power supply board used in ACS800 series AC drives. It converts incoming power into the stable low-voltage supplies required by the control electronics, IGBT gate drivers, and auxiliary circuits.

Technicians rely on this board for restoring drives that have power supply faults. It is a common spare part that keeps critical variable speed drives operational in manufacturing, pumping, and HVAC applications.

5. Troubleshooting Quick Reference

Symptom Possible Cause Relevance to this Part Quick Check Method Recommendation
Drive dead, no control power Failed APOW board ✅ High Check input voltage to board; measure output rails Replace APOW-02C if outputs missing
Intermittent control faults Degraded capacitors ✅ High Monitor voltages under load Replace board; consider preventive refresh
Fan not running Auxiliary output failure ✅ Medium Verify fan supply voltage at connector Check APOW outputs before fan replacement
Drive reports power supply fault Overvoltage or short ✅ High Review drive fault log Inspect board for damage; test outputs
No LEDs or partial power Input fuse or wiring ❌ Low Trace input from main bus Verify upstream supply first

Always discharge the DC bus before working inside the drive.

6. Frequently Asked Questions (FAQ)

Is this the complete power supply for an ACS800 drive? It is the main control power supply board. Larger drives may have additional power components — confirm your exact drive frame size and catalog number.

What condition are the units? New Original / New Surplus pulled from spares or lightly used systems. Each board is inspected, tested for output voltages, and cleaned before shipping.

Will APOW-02C work in my specific ACS800 model? It is used across many ACS800 configurations. Verify compatibility with your drive type (e.g., ACS800-02, -04, etc.) before ordering.

How do I install or replace it? Power off and lock out the drive. Discharge the bus. Remove the old board, install the new one matching connectors, and restore power. Follow ABB service manual torque specs.

Do you test these boards? Yes. We apply simulated load and verify all output rails are within specification. Test report available. Test videos and photos on request.

What warranty is provided? 1-year warranty against defects in materials and workmanship when installed correctly. Contact us with drive fault details if issues arise.
