Sicon CMS modular UPS, special used to IDC data center, is a high-end product launched to market by sicon adopting “Energy saving, green, environmental protection” concept. It delivers the best combination of rectifier, filter, charger, inverter and intelligent power protection. Applying innovative current sharing rectifier control, master-slave synchronization in sequence control, multi-level decentralized control and 3-level sine wave modulation technology, it features great efficiency, flexibility and reliability, reduces the investment, operation, maintenance cost.
CMS series modular UPS is a new type modular UPS, which integrated digital technology and new semiconductor technology, can completely eliminate the impact of various grid problems on key loads. Adopting 75KVA power modules, it features high power density, reliable, high efficiency and intelligence, provides ideal power supply protection for customers’ large and medium places.


• Adopting modular structure, composed of monitor module, bypass module, control module and power module in parallel, power module N+X redundancy, hot swappable and scalable online.
