A front-maintenance high-density 1u power plug-in frame

Abstract

A kind of front maintenance high-density 1U power supply plug-in frame, including plug-in frame, the front of inside of plug-in frame is sequentially distributed with alternating current input terminal, rectifier, controller, control signal input and output interface and output switch breaker from left to right, the back of inside of plug-in frame is distributed rectification power backplate, control signal adapter plate, DC lightning protection plate and DC load power-off control panel respectively, rectification power backplate is connected with control signal adapter plate, DC lightning protection plate and DC load power-off control panel by copper bar assembly;The sidewall of outside of plug-in frame is fixed with '' L '' type mounting bracket, and identification label is hung on mounting bracket.The utility model arrangement is efficient and compact, from alternating current input to rectification output, signal control input and output and DC power control output are arranged in the front of plug-in frame, so that rectifier, controller and output switch breaker can be plugged from front maintenance, replace, very simple and convenient, easy to operate and maintain.
