Description
The R48-5800 rectifier converts 380~480 Vac 3-phase AC supply voltages into stable
nominal -48 VDC voltage adjustable to the needs of the application. The R48-5800 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.
