Overview

The CQ Series is a true online double-conversion UPS from 1 to 10kVA, protecting servers, LANs and precision equipment with zero transfer time. DSP control, a wide adjustable 40–70Hz input frequency range and an output power factor up to 1.0 (6–10kVA) keep mission-critical loads running through outages, sags and frequency drift.

An intuitive LCD panel, panel-settable parameters and RS-232 communication with optional SNMP make integration and remote monitoring straightforward.
