Description

Product Overview

The 125840-02 is the low‑voltage AC power input variant of the Bently Nevada 3500/15 power supply family for the 3500 machinery protection rack. It converts 110 VAC mains into multiple regulated DC rails to feed all monitors, relay modules and communication boards in the chassis. It occupies the dedicated half‑height power slot on the far left of the rack; dual power supplies can be fitted for redundant operation, supporting mixed AC/DC supply configurations. Hot‑swap capability allows replacement without shutting down the vibration protection system. It is widely deployed on gas turbines, steam turbines, centrifugal compressors and pumps in power plants, refineries and petrochemical facilities.
