Verity Emerson Communication Power Module R48-4000e 48V 4000W High Efficiency Rectifier Module
Description
The eSure R48-4000e high-efficiency rectifier is designed to convert standard AC supply voltages into stable nominal 48 VDC voltage that is adjustable to application needs. The R48-4000e is a constant power rectifier designed with the latest patented switchmode 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.
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 efficiency, 95.5%-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 / -40 °F to +75°C / 167°F) -meets the harshest climatic environment requirements.
