Rectifier

R48-3500e

Key Features

 3500 Watt high-efficiency rectifier designed for -48V DC power applications

 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 efficiency, approaching

97% – reduces power consumption for lower operating costs

 Hot pluggable – facilitates future extensions

 Wide input voltage range to operate in the most demanding environments where input voltage changes

 Wide temperature operating range (-40°C / -40°F to +75°C /

167°F) to meet the harshest climatic environment requirements

In addition to reducing power consumption and lowering operating cost, eSure ™ high-efficiency rectifiers offer superior performance and uncompromised reliability.

Description

The eSure ™ R48-3500e high-efficiency rectifier is designed to convert standard AC supply voltages into stable nominal -48V DC voltage that is adjustable to application needs. The R48-3500e 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.
