DC Power for

Business-Critical Continuity ™

eSure™ Rectifier

R48-2000e3

Key Features

High efficiency, above 96% – reduces power consumption for lower operating costs

Full output power (2kW) up to system and operating costs

High power density – reduced footprint allows installation in short-depth racks and cabinets

Wide input voltage range to operate in the most demanding environments

Hot pluggable – facilitates future expansions and easy maintenance

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

The 2000W high-efficiency eSure™ rectifier ( model R48-2000e3) is designed to convert standard AC supply voltages into stable nominal -48 V DC voltage that is adjustable to application needs. The R48-2000e3 i s 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.
