DC Power for
Business-Critical Continuity™
eSure™ Rectifier
R48-2000e3
Key Features
High efficiency, above 96% –
reduces power consumption
for lower operating costs
Full output power (2kW) up to
+65 ° C allows savings on climate
system and operating costs
High power density –
reduced footprint allows
installation in short-depth
racks and cabinets
In addition to reducing power consumption and
lowering operating cost, eSure™ high-efficiency
rectifiers offer superior performance and
uncompromised reliability.
Description
The 2000W high-efficiency eSure™ rectifier ( model R48-2000e3) is designed to convert
standard AC supply voltages into stable nominal -48 V DC voltage that is adjustable to
application needs. The R48-2000e3 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.
Wide input voltage range to
operate in the most
demanding environments
Hot pluggable – facilitates
future expansions and easy
maintenance
Compliant with global
standards – delivers quality,
performance and reliability no
matter what the application or
location demands
