EA660 50-600kVA Online Modular UPS
The EA660 modular UPS is ideal for reliable, cost-saving, intelligent, and easy solutions. It ensures that a scalable, secure, high-quality power supply is available for any critical high-density computer and IT environment applications, such as data centers and other critical loads.
Product Description
The EA660 modular UPS is a scalable three-phase uninterruptible power supply system with DSP technology and provides true on-line double conversion power protection. The available UPS power and redundancy level can expand vertically from 50 to 600 kVA/600 kW in one single power cabinet, and four power cabinets can be connected in parallel, increasing the capacity up to 2.4 M kW. It features a modular hot-swappable design; all modules support plug & play, including power modules, bypass modules, and control modules, which simplifies UPS servicing and maintenance.
