Emerson R48-5000A RECTIFIER MODULE
Product description:
The R48-5800A rectifier converts 380 to 415 VAC 3-phase supply voltages into stable
nominal -48V DC voltage adjustable to the needs of the application. The R48-5800A is a
constant power rectifier designed with the latest patented switch-mode technology
using DSP (Digital Signaling Processor) functionality for efficient operation.
For a larger load capacity, rectifiers can be connected in parallel and intelligent control
can be added with the help of a separate controller
Product features:
1.DSP (Digital Signaling Processor)-means fewer components, optimized operation and active load sharing for increased reliability
2.Delivers quality, performance and reliability no matter what the application or location demands
3.High efficiency, up to 92% reduces power consumption for lower operating costs
4.Hot pluggable-facilitates future extensions.
5.Wide input voltage range operates in the most demanding environments where input voltage changes
6.Wide temperature operating range from -40°C to +65°C / -40°F to +149°F meets the harshest climatic environment requirements
