2U 110Vdc 20A rectifier module

RM11020-A is a power supply device that converts standard AC voltage into stable 110Vdc for communication power supply system.

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.
