DC Power for
Business-Critical Continuity
R24-2500
Rectifier, 105A
+24 V DC, 2500W
Description
The R24-2500 rectifier converts 90 to 275V AC supply voltages of standard frequency
into stable nominal +24 VDC voltage that is adjustable to the needs of the application.
The R24-2500 is a constant power type rectifier designed with the latest patented
switch mode technology using DSP (Digital Signaling Processor) functionality for
efficient operation. For a larger load capacity, the rectifier can be connected in parallel
and intelligent controls can be added with the help of separate controllers.
Features and Benefits
High power density - up to 7.5 kW in
a 1U high 19 - inch shelf, and 10 kW
in a 1U high 23 - inch shelf, means
more space for revenue - generating
equipment
Temperature - controlled cooling
fan-reduces noise levels and
increases fan longevity
Full power 2500 W at +24 V outputenables the start of deep discharged
battery systems
High efficiency up to 91% - reduces
power consumption for lower
operating costs
Hot swappable - makes rectifier
removal and installation easy to
facilitate upgrades and repairs
without shutting down the system
Wide input voltage range - maintains
operation despite AC grid abnormal
operating conditions
Wide temperature operating range operates in the most demanding
environments where the operating
temperature ranges from -40 / 40 F to +75 / +167 F
Zone 4 seismic - delivers ruggedness
and dependability in regions subject
to earthquakes
NEBS level 3 certified - meets the
most demanding level of compliance
required in the telecommunications
industry
Compliant with global standards delivers quality, performance and
dependability
