Rectifier, -48 V DC, 400 W
Features and benefits
Low rectifier/subrack height –
minimize space needed for power in
embedded applications
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
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 +75°C / 167°F) – meets
the harshest climatic environment
requirements
The R48-400 rectifier converts standard AC supply voltages into
stable nominal -48 V DC voltage adjustable to the needs of the
application. The R48-400 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.
