Product Introduction
The Bently Nevada 3500/15-02-02-00 (125840-01) is a High Voltage AC Power Input Module (PIM) for the 3500 machinery protection rack. It is used with the 3500/15 AC Power Supply to accept high-voltage AC input and provide rack power for monitoring modules.
Buyers specify this PIM when the site power is 220 Vac nominal and the rack uses the high-voltage AC input option. The key points are input range match, correct revision for the installed supply, and confirmation that the rack uses left-side power slots.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Supply OK LED off | No AC input or PIM fault | ✅ High | Measure 175–264 Vac rms at PIM terminals and check for breakers/fuses | Verify incoming AC before replacing the PIM or supply |
| Rack loses power under load | Weak AC source or PIM not rated for load | ✅ Medium | Check mains voltage under load and monitor PIM temperature | Confirm upstream power margin and ventilation |
| Redundant supply not taking over | PIM wiring or second supply fault | ✅ High | Test redundancy by removing one supply per approved procedure | Verify wiring and backup supply output |
| Supply OK LED on but modules fail | Internal supply fault or backplane issue | ✅ Medium | Check output rails on the rack and test with a known-good supply | Replace the power supply first, then check backplane |
| Overheating at PIM or supply | Poor airflow or high ambient temp | ✅ Medium | Inspect cabinet ventilation and measure ambient temperature | Improve cooling and ensure rack slot is clean |
| Input voltage specification mismatch | Old PIM supply revision vs. new input range | ✅ High | Compare PIM and supply revision letters with nominal input | If pre-Rev R (PIM) and pre-Rev M (supply), input must be 175–250 Vac rms |
If you get stuck, contact technical support with photos of the nameplate, PIM and power supply revision letters, wiring, and any fault indicators.
Frequently Asked Questions (FAQ)
Q: Is 125840-01 the PIM or the power supply?
A: 125840-01 is the High Voltage AC Power Input Module (PIM). The power supply is the 3500/15 AC module that pairs with this PIM.
Q: What input voltage does this PIM use?
A: It is rated for 220 Vac nominal, with an input range of 175–264 Vac rms. If your installed PIM is pre-Rev R and the supply is pre-Rev M, the allowable range is 175–250 Vac rms.
Q: Can I mix AC and DC supplies in the same rack?
A: Yes, the 3500 rack can have one or two power supplies with any combination of AC and DC. Either supply can power the full rack; the second acts as a backup.
Q: Is the 3500/15 PIM hot-swappable?
A: In a redundant configuration, the rack can stay up while one supply/PIM set is removed under the proper procedure. Do not guess on procedure; confirm your rack setup first.
Q: Are all 3500/15 PIMs interchangeable?
A: No. AC and DC options are different, and even AC PIMs have different voltage options (high-voltage vs. low-voltage). The suffix and revision matter.
Q: What should I check before replacement?
A: Confirm input voltage and frequency, PIM and supply revision letters, physical condition, and whether the rack uses single or dual supply. Also inspect terminals and backplane for heat damage or corrosion.
Q: Why does this listing show a lower price than OEM new stock?
A: Because it is typically surplus inventory from excess or retired systems. The price is acceptable as long as the seller documents condition, revision, and exact part number.
