eSure™ Rectifier
DC Power
for Business-Critical Continuity™
R48-3200e
eSure™ Rectifier
-48 V DC, 3000 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
2
nominal-48V DC voltage adjustable to the needs of the application. The R482
mode technology using DSP (Digital Signaling Processor) functionality for
control can be added with the help of a separate controller.
Compliant with global standardsdelivers quality, performance
and reliability no matter what the
application or location demands
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 +65°C / 149°F) -meets
the harshest climatic environment
