1.3General Description

EPS 7000 is a family of compact, high-efficiency uninterruptible power systems. Standard power ratings for single- module systems range from 300 to 500 kVA. EPS 7000 are optimized for compatibility with non-linear computer-type loads. Computer-aided UPS diagnostics and modular construction assures that any required service on the UPS can be identified and completed rapidly. Remote system monitoring, remote annunciation of UPS performance signals, and telecommunication capabilities allow total control of the UPS by the user.
