Universal AC input – Typically accepts 100–240 VAC, 50/60 Hz, making it easy to deploy across sites.
Rack-wide power distribution – Feeds the 3500 backplane rails for all monitoring/protection modules.
Redundancy-ready – Supports dual power module configurations with automatic switchover for higher availability.
Hot-swappable design – You can replace it online (with a second supply active) to minimize downtime.
Front-panel status LEDs – Quick visual checks for OK/Power; technicians usually know the rack health at a glance.
No field I/O – Power-only module; simplifies commissioning and reduces wiring errors.

The 129489-01 is typically used anywhere a Bently Nevada 3500 rack is installed for rotating machinery protection and condition monitoring:
Oil & Gas: compressor trains, gas turbine packages, pump skids
Power Generation: steam/gas turbines, balance-of-plant assets
Petrochemical & Refining: critical pumps, blowers, fans
Pulp & Paper, Mining, Steel: large motor-driven equipment lines
A maintenance lead recently told us their team swapped a failed supply in under 3 minutes with no trip, thanks to the redundant setup—exactly the kind of field result this module is built for.
Reliability first – Proven in harsh industrial environments; simple, robust design reduces failure points.
Compatibility assured – Purpose-built for the 3500 series; no adapters, no guesswork.
Reduced downtime – Hot-swap and redundancy usually mean maintenance windows can be measured in minutes.
Lifecycle support – Widely stocked; easier spares planning across multiple sites.
Total cost control – Less emergency callout time and fewer unexpected trips typically offset the spare inventory cost.
Cabinet & ventilation – Install in a standard 3500 rack within a clean, ventilated control cabinet. Maintain ambient temperatures within typical control room ranges.
Power feed – Provide a stable AC source; where possible, use UPS or conditioned power. Proper grounding and protective earth are essential.
Redundancy – For critical assets, fit a second 129489-01 in the rack. Verify automatic switchover via front-panel indicators.
Wiring – Terminate AC input per the rack manual; check torque values and insulation clearances. Keep power and sensor wiring segregated.
Safety – De-energize the rack before single-supply replacement. If hot-swapping, ensure the redundant supply is healthy and the rack is in OK state.
Routine care – Quarterly visual checks for dust; clean with dry air. Inspect terminals for looseness. No calibration or firmware updates are required for this power module.
