Description
Product Overview
The Bently Nevada 127610-01 is the 3500/15 half-height AC power supply module for the Bently Nevada 3500 series machinery protection and vibration monitoring rack. It converts mains AC input to stable internal DC rail power for all 3500 I/O, processor and communication cards. Commonly deployed in turbines, compressors, pumps and rotating machinery protection systems in power generation, oil & gas and petrochemical plants. This part has been phased out by Bently Nevada; the universal AC replacement is 106M1079-01. Redundant dual PSU installation is supported for high availability protection racks.

Key Features
- Half-height hot-swappable power supply for 3500 machinery monitoring racks, occupies dedicated left-hand rack slots.
- Wide universal AC input range, works with global plant mains voltage without manual tap adjustment.
- Built-in overvoltage, overload and short-circuit protection to safeguard backplane and monitoring I/O modules.
- Redundant dual power supply architecture capability; either supply can sustain full rack load for fault tolerant operation.
- Front panel Power OK LED provides quick visual health status for maintenance technicians.
- Designed for continuous 24/7 operation in critical rotating machinery protection systems.
- Requires matching rear Power Input Module (PIM) mounted on the back of the 3500 rack.
Installation Notes
- Install only in the dedicated leftmost PSU slots of standard Bently Nevada 3500 rack.
- Match the front 127610-01 module with the corresponding rear PIM assembly.
- This module is hot-swappable under controlled maintenance conditions, follow plant LOTO procedures.
- For redundant configuration, connect each PSU to separate independent AC power sources.
- Keep AC input wiring separated from vibration transducer signal cables to reduce EMI.
- Verify total rack power consumption before commissioning to avoid PSU overload.
- The part is end-of-life, use 106M1079-01 as direct replacement for new spares.
Testing Procedure
- Visual inspection: Check housing, edge connector, front panel LED for physical damage, corrosion or bent pins.
- Insert module into 3500 rack PSU slot, connect rated AC mains input.
- Energize AC supply and confirm Power OK LED illuminates steadily.
- Use multi-meter to measure internal DC rail output voltage under normal load.
- Load test with full rack I/O complement, confirm stable output without voltage drop or fault alarms.
- Simulate AC input loss to validate redundant failover function in dual PSU racks.
- Record voltage readings, sign test report and tag module for spare inventory.
