CMS UPS units are non-isolated, industrial level, green UPS, adopting advanced modular power protection concept. CMS Modular architecture can scale power as demand grows or as higher levels of availability are required. CMS UPS is industry-leading efficiency, availability, and performance for small, medium, and large data centers and mission critical environments.

Automatic control system of data rooms, communication rooms and power industry, power supply system of petrochemical industry, security prevention system of intelligent building and other mission critical environments.


  1.Rational redundant structure
  2.UPS module: 40kVA; System: 120kVA
  3.Online hot swappable: all module online hot swappable, maintenance, expansion.
  4.Great performance index:
     Overall efficiency ≥ 95%(AC-AC), inverter efficiency ≥ 98%(DC-AC), THDI ≤ 5%, and input PF﹥0.99, N+X module-level redundancy UPS System
  5. Multi-level decentralized control technology and Master-slave synchronization in sequency control which result in eliminate system failure bottleneck
  6.Each module automatically even shares the input and output current, all UPS modules share batteries
  7. Battery management: Battery discharge management, auto-transfer between floating and even charging, temperature compensation
  8.Space-saving high density design, Rack-based for agility and aesthetics
  9. Standard configuration: Manual maintenance bypass, SPD(Class C), RS232, RS485 Communication ports, SNMP (optional), Remote monitor software, dry contacts
  10. Optional configuration:
        EPO, Input/output Transformer, Battery Bank, IPDS (Intelligent Power Distribution System)


Small and medium-sized data center,  government, telecom, bank, security, transportation, broadcast &TV network, HealthCare, Communication, E-business, Finance, etc.
