Delta Electronics FR 2000 User Manual

The FR 2000 Rectifier

Description:

The FR 2000 rectifier is a single phase, hot-pluggable, fan-cooled rectifier. The constant output power characteristic
supplies the specified power over the full output voltage range. The benefit is an optimised modular system design
(fewer number of modules) and matches the supply requirements for state-of-the-art telecom equipment. This
performance as well as the extended temperature range, wide input voltage range, high power density and
advanced technology are the key factors of the success of this rectifier and it offers a cost effective and reliable
solution.
The rectifier meets the requirements set by the telecommunications standards.
