Inabikari EA660 50KVA~600KVA

EA660 is the third generation of three phase high frequency on-line double-conversion modular UPS. Its single unit is extendable to 600 KVA, system capacity can be expanded to 2.4 MVA constructed by each power module 50 KVA. All internal modules (Power module, bypass module and control module) are modularly designed and hot-swappable.

Characteristics
