MR483000HG2B-GS High-Efficiency 3000W Rectifier Module, 85–290VAC Input, 42–58VDC Output, Forced Air Cooling, CE/UL Certified

Product Overview

MR483000HG2B-GS is a power supply device that converts standard AC voltage into stable 48Vdc for communication power supply systems.
For a larger load capacity, the rectifier modules can be connected in parallel, or an additional independent monitoring module can be used for intelligent control.

The rectifier module is a plug-in modular unit designed to be compatible with racks and cabinets.
