Frequently Asked Questions (FAQ)

1. Why use 125 VDC instead of 24 VDC?

125 VDC minimizes current draw for long cable runs and provides cleaner power for signal-sensitive applications.

2. Does this work with existing 24 VDC 3500 racks?

Yes – rack wiring must be compatible, but module is plug-compatible with 3500 slots.

3. Can it be redundant?

Yes, install two in parallel and they automatically share and switch if one fails.

4. Is it hot-swappable?

Absolutely. It can be replaced without shutting down the rack.

5. How do I check module status?

Two LEDs: Green (power OK), Red (fault condition).

6. What power protections are included?

Includes protections for voltage, current, and temperature anomalies.

7. Can I use it in explosive environments?

Yes, certified CE, UL, CSA, RoHS; suitable for zone-rated applications depending on rack housing.

8. Does output stay stable under load changes?

Yes, it maintains regulated 125 VDC even under varying output loads.

9. Does it need any special tools?

All front-panel connectors allow tool-free insertion and removal.

10. Will use of this module impact other devices?

Only if other modules expect 24 VDC. Use only within racks designed for 125 VDC power rails.
