Overview

The DP-240-48 industrial DIN-rail power supply is designed and manufactured for industrial applications. It can be mounted on DIN rail TS35/7.5 or TS35/15, which saves installation space and facilitates onsite network deployment.

Adopting a metal enclosure,the DP-240-48 delivers electromagnetic shielding performance with good vibration and shock resistance. Its industrial fan-less design eliminates potential failure points caused by fan stall. It supports long-term stable, reliable and safe operation in various harsh industrial environments, and provides a high-reliability and high-efficiency power supply solution for industrial applications.
