Bently Nevada 3500/15 Redundant AC/DC Power Supply Module for 3500 Machinery Protection Rack

 Product Description

3500/15 is a half-height dedicated power supply module for Bently 3500 series turbomachinery monitoring racks, manufactured in USA. It converts wide-range AC/DC input into stable internal bus voltage to power all monitor, I/O and communication cards inside the rackBaker Hugh....

It supports single or dual redundant installation: lower slot as primary power, upper slot as hot backup. With two modules installed, either can fully drive the whole rack, and hot-swap replacement is allowed without system shutdown. Multiple input variants are available: universal AC, high voltage DC and low voltage DC to fit different plant power conditions. All boards adopt conformal coating to adapt to high-vibration turbine and compressor rooms.
