OPUS C DC Power Systems MRC Rectifiers

Modular Convection Cooled Rectifiers 1600W

Efore’s MRC AC/DC rectifier series is specifically designed and optimized for demanding industrial and telecom applications. Compatible with the complete OPUS C product family, these high-efficiency fanless rectifiers offer reliable and efficient performance for telecom operators and industrial manufacturers.

The MRC rectifiers deliver 1600 watts of output power at 48V, 60, 110, 125 and 200 VDC. The 24 VDC version of the rectifier provides 1100 watts of output power. Rectifier input is single phase at 140 – 275 VAC with convection cooling.The MRC series rectifiers can be operated with either the VIDI+ system controller or as standalone modules with or without battery backup.
