Excellent Performance, Outstanding Metrics

Ultra-low output voltage harmonic distortion effectively protects loads while reducing energy consumption

Optimized structural design that is small, convenient, and reduces space usage

Powerful overloading capacity; can provide stable uninterrupted power for 10 minutes at 125% overloading to ensure equipment operates normally and safely

High efficiency fan cooling; low noise for the entire system provides an environmentally friendly and comfortable working environment


Economy Mode, Significant Energy Savings

When the power quality from the mains grid is high, ECO mode can be used to provide power to the load which greatly improves overall efficiency, resulting in significant energy savings and reduced operation costs


Convenient Operation, Efficient Maintenance

Modularized design makes cabinet maintenance even more convenient

Components can be directly replaced which greatly reduces maintenance costs and average maintenance time resulting in high maintenance efficiency


Multi-level Protection, Safe Operation

Automatic detection upon startup which discovers hidden faults in a timely manner to ensure equipment safety and avoid unnecessary loss

Complete protection and warning function sets off a sound and light alarm immediately to implement real-time protection for a peace of mind


Battery Management Self Developed and Patented Technology

Has DC start so that UPS can start normally even when there is a power grid blackout

Incoming electricity automatically restores battery group charging without the need for manual intervention

Supports battery temperature compensation which extends battery life


Ultra-Long Backup Time, Battery Endurance

The backup time of the standard models are the best in the industry and provides longer power time and protection for electrical equipment Backup time can also be configured according to user’s actual requirements which ensures user’s important loads continue to function as required
