Emerson, emerson rectifier module R48-1800A 48V 1800W for Telecom


Features & Benefits:


1.  Optimized depth reduced footprint allows installation in short-depth racks and cabinets

2.  DSP (Digital Signaling Processor) means fewer components, optimized operation and active load sharing for increased reliability

3.  High efficiency, up to 91% reducespower consumption for lower operating costs

4.  Wide temperature operating range (-40 C / -40 F to +80 / 176 F)-meets the harshest climatic environment requirements




The R48-1800A rectifier converts standard AC supply voltages into stable nominal -48 VDC voltage adjustable to the needs of the application.


The R48-1800A 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.
