Emerson R48-2000A3 R48-2000e3 rectifier
The eSure™ R48-2000e rectifier converts standard AC supply voltages into stable nominal-48V DC voltage adjustable to the needs of the application. The R48-2000e is a constant power rectifier designed with the latest patented switch-mode technology using DSP (Digital Signaling 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
eSure™ Rectifier
-48 V DC, 2000 W
- 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
- Compliant with global standards-delivers quality, performance and reliability no matter what the application or location demands
- High efficiency, 96.5%-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 +80°C / 176°F) -meets the harshest climatic environment requirements
