Original Vertiv Emerson Rectifier Module R48-2000e Supply

Vertiv eSure R48-2000e rectifier converts standard AC supply voltages into stable nominal -48V DC voltage adjustable to the needs of the application. Emerson R48-2000e is a constant power rectifier designed with the latest patented switch-mode technology using DSP (Digital Signal Processor) functionality for efficient operation. For a higher load capacity, rectifiers can be connected in parallel and intelligent control can be added with the help of a separate controller
