Bently Nevada 3500/15-03-03-00 129486-01 Power Supply Module

Bently Nevada 3500/15-03-03-00 (129486-01) is a dual redundant power supply module for the 3500 machinery monitoring system. It converts AC or DC input power into stable internal rack bus voltage to feed all monitoring cards, featuring built-in fault detection, overvoltage, overcurrent and short-circuit protection for continuous safe operation.

This module supports hot-swap replacement without powering down the whole rack. It can work in simplex or redundant parallel mode, status and fault alarms are uploaded to the 3500 system host. It is widely used on turbine, compressor and pump condition monitoring racks in power and petrochemical plants.
