eSure™ Rectifier
DC Power
for Business-Critical Continuity™
R48-4000e
eSure™ Rectifier
-48 V DC, 4000 W
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
Description
The eSure™ R48-4000e rectifier converts standard AC supply voltages into stable
nominal-48V DC voltage adjustable to the needs of the application. The R484000e is a constant power rectifier designed with the latest patented switchmode
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.
High efficiency, 95.3%-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
