Vertiv / EmersonThe eSure R48-4000e rectifier converts standard AC supply voltages into stable nominal-48V DC voltage adjustable to the needs of the application. The R48- 4000e is a constant power rectifier designed with the latest patented switchmode technology using DSP (Digital Signaling Processor) functionality for eicient 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.
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 sharing for increased reliability
High eiciency, 95.3%-reduces power consumption for lower operating costs
Hot pluggable-facilitates future extensions
Wide input voltage range-operates in the most demanding environm ents where input voltage changes
Wide temperature operating range (-40°C / -40 °F to +75°C / 167°F) -meets the harshest climatic environment requirements
