Emerson NetSure 801 R48-5800L, NetSure 801 DC Data Sheet
R48-5800L
DC Power for
Business-Critical Continuity™
Rectifier, 120A
-48VDC, 5800W
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
Compliant with global standards
– delivers quality, performance
and reliability no matter what the
application or location demands
High efciency, up to 92% – reduces
power consumption for loweroperating
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
requirements
Description
The R48-5800L rectier converts 145V to 264 V 3-phase AC supply voltages
into stable nominal -48 V DC voltage adjustable to the needs of the application.
The R48-5800L is a constant power rectier designed with the latest patented
switch-mode technology using DSP (Digital Signaling Processor) functionality
for efcient operation. For a higher load capacity, rectiers can be connected
in parallel and intelligent control can be added with the help of a separate
controller.
