One honest note up front. Reseller data on this part is inconsistent, and some pages paste generic filler instead of a real datasheet. Confirm the nameplate, output voltage, and connector pinout against your cabinet drawing before ordering.
Product Introduction
Westinghouse 1X00416H01 is a WH5-2FF style power module feeding Ovation cabinet electronics. It takes wide range AC mains and holds regulated DC output while handling short circuit, over voltage, and under voltage faults.
Why it matters. A drifting supply kills controllers slowly. Ripple creeps into analog readings, drops cause random I/O faults, and crews blame cards. This unit covers roughly 90 to 264VAC input with a claimed -40 to 75C operating range.

Quality Control Process
Power modules fail through heat and ripple, so we test under load, not idle.
- Nameplate audit. Output voltage, wattage, and connector type must match your cabinet drawing. Relabeled stickers get rejected immediately.
- Input and rail inspection. A Fluke multimeter checks for shorts across input and output before any power is applied.
- Cold start check. We energize with a variac from low voltage up, watching for chatter or a hard no start.
- Load bank test. The unit runs at 50, 80, and 100 percent rated load. We log voltage sag at full load.
- Ripple measurement. An oscilloscope with an AC coupled probe measures peak to peak ripple. Anything spiky gets rejected, since ripple corrupts analog inputs.
- Thermal soak. Two hours under load with a thermal camera checking hot spots on transformers and heat sinks.
- Protection trigger test. We short the output briefly through a current limiting bulb and confirm shutdown instead of smoke.
- Insulation check. A Megger verifies input to chassis integrity on metal housed units.
- ESD and moisture packaging. Anti-static shielding bag, desiccant, humidity indicator, rigid double box.
Replacement Pitfall Guide
❗ Assuming any WH series supply drops in. Cabinet families often mix MAGNETEK WH1-2FF 24V units and WH3A-2DF pluggable supplies, and pinouts differ. Reverse polarity kills controller cards instantly.
❗ Sizing by nameplate wattage only. Inrush from controllers, fans, and relay banks can trip a supply rated just above steady draw. Add real margin, then measure actual cabinet current.
❗ Ignoring cooling and derating. A sealed cabinet at 55C derates most supplies hard. Reseller ranges claiming -40 to 75C rarely account for still air inside a closed enclosure.
❗ Skipping ripple checks after a swap. If analog points drift or DI channels ghost trigger post replacement, scope the rail before blaming I/O cards. That mistake cost one crew a full weekend.
❗ Running without input protection. A missing fuse or weak surge device lets line transients destroy the module and whatever it feeds.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
| Original Model | Replacement / Successor Model | Compatibility Level | Migration Notes |
|---|---|---|---|
| 1X00416H01 | Same part, later date code | Direct | Confirm nameplate, output voltage, connector |
| 1X00416H01 | 1X00024H01 MAGNETEK WH1-2FF | Needs Adaptation | 24V output with auxiliary, different rail and wiring |
| 1X00416H01 | 1X00163H01 MAGNETEK WH3A-2DF | Needs Adaptation | Pluggable form factor, verify backplane fit |
| Failed OEM supply | Modern DIN rail 240W industrial supply | Needs Adaptation | Match voltage, margin, mounting, and hold-up time |
| Redundant cabinet feed | Dual supply with ORing diodes or redundancy module | Needs Adaptation | Prevent backfeed between supplies |
| Aging Ovation cabinet with scarce spares | Full cabinet power retrofit kit | Needs Adaptation | Recheck grounding, fusing, and total draw |
- Expect measurable voltage sag at full load, so verify regulation under real cabinet current rather than at idle.
- Keep peak to peak ripple low and stable, since rising ripple often shows up first as noisy analog readings.
