DC Power for
Business-Critical Continuity™
eSure™ Rectifier
R4811600, R4812000e and R4812000Le
Key Features
High-efficiency rectifier designed
for -48V DC power applications
Optimized depth –
small 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 quality,
performance and reliability no
matter what the application or
location demands
In addition to reducing power consumption and
lowering operating cost, eSure™ high-efficiency
rectifiers offer superior performance and
uncompromised reliability.
Description
High-efficiency eSure™ rectifiers R48-11600, R48-12000e and R48-12000Le are designed
to convert standard AC supply voltages into stable nominal -48V DC voltage that is
adjustable to application needs. These rectifiers are constant power rectifiers 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,reduces power
consumption for lower operating
costs,see diagram.
Hot pluggable – facilitates
future expansions
Wide input voltage range to
operate in the most
demanding environments
where input voltage changes
