DUCS Telecom Rectifier System

DUCStelecom rectifier system is designed for applications of small telecommunication. For detailedinformation, this product is composed of three DES rectifier modules, onemonitor module and power distribution section and the depth of 19”2U sub-rack is 255mm. With regard to configuration, it can supplymaximum 48VDC 90A 4.8kwwith one AC input MCB, four MCBsprotected outputs and one battery MCB. Besides that, RS485 and 6 groups of drycontacts are available for customers to choose.
