Tips:This product is the power supply for the communication base station, which should have a communication connection with the chassis. If you do not have a communication connection, the yellow light will flicker, which is a normal phenomenon and does not affect the normal power output.
Feature
High efficiency, reduces power consumption for lower operating costs
Full output power (3kW) up to +45C allows savings on the climate system and operating costs
Wide input voltage range to operate in the most demanding environments
Hot-pluggable facilitates future expansions and easy maintenance
Compliant with global standards deliver quality, performance, and reliability no matter what the application or location demands
Description
The 3000W high-efficiency rectifier ( model R48-3000e3) is designed to convert standard AC supply voltages into stable nominal -48 V DC voltage that is adjustable to application needs.
The R48-3000e3 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.
