Bently Nevada 114M5329-01 3500 Series AC Power Input Module
The Bently Nevada 114M5329-01, also cataloged as the 3500/15 AC Power Input Module, operates as a dedicated hardware component for converting universal AC supply into regulated backplane power within Bently Nevada 3500 Machinery Protection System racks. Accepting an input voltage range of 85 to 264 VAC at 47 to 63 Hz, this power module delivers up to 90 W of regulated, isolated power to the rack backplane bus while filtering out line noise and voltage transients.

Rotor Dynamics and Gap Voltage Validation Parameters
The 114M5329-01 AC Power Input Module conditions incoming AC power lines to isolate sensitive measurement channels from electrical grid disturbances. Clean backplane power delivery enables precise eddy-current probe scaling (200 mV/mil or 7.87 V/mm) and maintains consistent probe gap voltage validation (-10 VDC targets) across adjacent monitoring modules. High-frequency line filtering suppresses cross-talk and power line transients, preserving signal integrity so downstream TSI modules can accurately track shaft displacement, phase angles, and overall rotor dynamics during transient and steady-state conditions.
Frequently Asked Questions
Q: Does the 114M5329-01 module support live hot-swapping inside a powered 3500 rack?
A: Yes, in a dual-redundant power configuration, personnel can hot-swap a single 114M5329-01 module while the secondary power supply maintains system operation without interrupting monitoring.
Q: Is it permissible to operate one AC power module and one DC power module in the same 3500 rack?
A: Yes, the 3500 rack backplane supports mixing one AC Power Input Module and one DC Power Input Module to accommodate dual independent power sources.
Q: How can technicians visually verify proper power delivery from the 114M5329-01 module?
A: The module front panel includes status LEDs where a solid green light confirms output voltage parameters remain within nominal operating limits for the rack backplane.
Field Installation Guidelines
When installing or servicing the Bently Nevada 114M5329-01 AC Power Input Module, follow these physical procedures:
- Confirm that the incoming utility supply voltage measures within the rated 85 to 264 VAC limits before connecting field wiring.
- Align the module card edges with the left-most power slot guide tracks inside the 3500 chassis.
- Slide the assembly inward until the rear connectors interface fully with the rack backplane power bus.
- Tighten the top and bottom captive retaining screws to 0.6 N m torque to secure chassis grounding.
- Secure AC supply conductors to the rear terminal connections, ensuring ground conductors connect directly to the rack earth ground lug.
