DC Power for
Business-Critical Continuity™
Rectifier
R48-3200
Key Features
n3200 watt rectifier
designed for -48V DC
power applications
nOptimized depth –
reduced footprint allows
installation in short-depth
racks and cabinets
nDSP (Digital Signaling
Processor) means fewer
components, optimized
operation and active load
sharing for increased
reliability
The reliable and efficient R48-3200 rectifier reduces
power consumption, lowering operating cost.
Description
The 3200 watt rectifier (R48-3200) is designed to convert standard AC supply voltages into stable nominal -48V DC voltage that is adjustable to application needs.
The R48-3200 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.
nCompliant with global
standards – delivers quality,
performance and reliability no
matter what the application
or location demands
nHigh efficiency, up to 92%,
reduces power consumption
for lower operating costs
nHot pluggable – facilitates
future extensions
nWide input voltage range –
operates in the most
demanding environments
where input voltage changes
nWide temperature operating
range (-40°C / -40°F to +75°C /
167°F) meets the harshest
climatic environment
requirements
