Bently Nevada 3500/15 125840-02 Dual Power Supply Module

Bently Nevada 3500/15 125840-02 is a redundant dual power supply module designed for the Bently Nevada 3500 machinery monitoring rack. It supplies stable DC power to all installed monitoring modules, supporting redundant power input to guarantee continuous operation for critical rotating machinery protection systems.

This power module supports hot swap and built-in power fault diagnostic alarms. It can accept AC or DC input options and automatically switch between dual power paths in case of one source failure, widely used for vibration monitoring cabinet maintenance, spare parts replacement and machine protection system retrofit projects.
