FAQ – Frequently Asked Questions
What is the output rating of the 5466-1001?
24 VDC at 16 amps continuous.
Can I replace this unit while the system runs?
Yes. Redundant configuration supports hot-swapping.
Why is the red Power Supply Fault LED on?
A short circuit exists on an external device. Check wiring first.
How do I reset the module after a fault?
Turn off input power for 60 seconds. Then restore power.
What happens if one redundant supply fails?
The other supply handles the full load automatically.
Can I connect both supplies to one breaker?
No. Use separate sources for redundancy to work properly.
Does this module work with the MicroNet Plus?
Yes. It is fully compatible with MicroNet Plus systems.
What is the typical lifespan under normal use?
Over 10 years in a clean, temperature-controlled panel.
Is there a lighter alternative for small systems?
Use 5466-1000 for lower power needs. This model is 22 kg.
Does Woodward still support this part?
Yes. Manuals 26167V1 and 26166V2 are available.
Selection Guide
– Choose 5466-1001 for high current (16A) and redundant systems. – Choose 5466-1000 for lower current (approx 8A) and simplex systems. – Use one supply per chassis for non-critical applications. – Use two supplies per chassis for 24/7 or safety-critical plants. – Verify your chassis has two free slots for installation. – Confirm input source can deliver 24VDC at 20A minimum.
