Original new EMERSON R48-1000A R48-1000 rectifier module, 48 VDC 20A/1000W.
Description:
Emerson R48-1000 rectifier converts standard AC supply voltages into stable nominal -48 VDC voltages adjustable to the needs of the application. The R48-1000 is a constant power rectifier designed with the latest patented switch-mode technology using Digital Signal Processing (DSP) functionality for efficient operation. For a larger load capacity, rectifiers can be connected in parallel and intelligent control can be added with the help of a separate controller.
