EA660 20KVA~400KVA


PF 1.0


With extendable capacity up to 400KVA/400KW in each closet and full DSP control technology, EA660 series is the third generation of three phase high frequency modular UPS. All internal modules(power module, charger module and monitor module )are modularly designed and hot swappable. In addition, they are constructed with small modules, assuring both system compactness and reliability. Its full isolation design between fragile components and air flue makes the best of combination of reliability, functionality and flexibility. Moreover, this system adopts advanced ”N+X” wireless parallel and redundancy technology, avoiding single point failure, and further strengthening the reliability.
