Vertiv/Emerson R48-5800e Rectifier ModuleProduct description:
 
The eSure R48-5800e rectifier converts 260 to 530Vac 3-phase AC supply voltages into stable nominal-48V DC voltage adjustable to the needs of the application. The R48-5800e 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
 
Product features:
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. Compliant with global standards- delivers quality, performance and reliability no matter what the application or location demands
4.High efficiency, near 96.2%-reduces power consumption for lower operating costs
5. Hot pluggable-facilitates future extensions
6.Wide input voltage range-operates in the most demanding environments where input voltage changes
7. Wide temperature operating range (-40°C / -40 °F to +65°C / 149°F) -meets the harshest climatic environment requirements
