Rectifier
R48-3500e
Key Features
 3500 Watt high-efficiency
rectifier designed for -48V DC
power applications
 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
 Compliant with global
standards – delivers q
uality,
performance and reliability no
matter what the application or
location demands
 High efficiency, approaching
97% – reduces power
consumption for lower
operating costs
 Hot pluggable – facilitates
future extensions
 Wide input voltage range to
operate in the most
demanding environments
where input voltage changes
 Wide temperature operating
range (-40°C / -40°F to +75°C /
167°F) to meet the harshest
climati
c environment
requirements
In addition to reducing power consumption and
lowering operating cost, eSure
™
high-efficiency
rectifiers offer superior performance and
uncompromised reliability.
Description
The eSure
™
R48-3500e high-efficiency rectifier is designed to convert standard AC
supply voltages into stable nominal -48V DC voltage that is adjustable to application
needs. The R48-3500e is a constant power
rectifier designed with the latest patent-
ed 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.
