FAQ

What is the primary function of the 125840-02?

This module acts as a power supply unit for Bently Nevada monitoring racks, converting AC line power into the necessary DC voltage required by the system's internal cards.

Is this module suitable for high-vibration environments?

Yes, the module is rated for 5g vibration resistance across a frequency range of 10-2000 Hz, making it suitable for standard industrial monitoring applications.

What should I do if the module fails to power up?

First, verify the input voltage at the terminals. Check the internal 250V fuse for continuity. If the fuse is intact and voltage is present but the unit remains unresponsive, the module may require replacement or factory service.
