Rectifier -48 V DC, 1700 W Features and benefits Optimized depth reduced footprint allows installation in short-depth racks and cabinets. DSP (Digital Signaling Processor) means fewer components, optimized operation and active load haring for increased reliability. Compliant with global standards delivers quality, performance and reliability no matter what the application or location demands. High efficiency, up to 91% reduces power consumption for lower operating costs. Hot pluggable facilitates future extensions. Wide input voltage range operates in the most demanding environments where input voltage changes. Wide temperature operating range (-40°C to +80°C) – meets the harshest climatic environment requirements. AC input current limitation is possible on the rectifier. This function enables the user to employ 10 A AC breakers, or smaller, if desired. :9Fem[h\eh :9Fem[h\eh 8ki_d[iiø9h_j_YWb9edj_dk_jo 8ki_d[iiø9h_j_YWb9edj_dk_jo The R48-1800 rectifier converts standard AC supply voltages into stable nominal -48 V DC voltage adjustable to the needs of the application. The R48-1800 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.
