Energy conservation and high efficiency
Adopts advanced PFC control technology, the input power factor is greater than 0.99, which greatly
improves the use ratio of electric energy and reduces the load of power grid, and save the cost of
power distribution. The size of whole UPS is small, and the weight is light, calorific value is small,
which enhances the use ratio of environment and decrease the investment cost.
Smart fan speed control
The fan speed is adjusted automatically in accordance with the load status, which prolong fan life and
reduce noise.
ECO energy conservation mode design
The UPS is designed with ECO energy conservation mode. When the user power grid is good, if the
UPS operating in this mode, the bypass prior to output, and the efficiency can be 99%.When the
bypass voltage or frequency out of normal range and cannot satisfy the user’s power supply
requirement, it will switch to inverter output, and this guarantee the reliability of power supply and
also, save energy.
Manual maintenance bypass design
It designs manual maintenance bypass channel to ensure the UPS supply power for load while
maintenance, which greatly improve the system operation reliability and maintainability.
Reliable EMC performance
Pass the authority institution and professional test on EMC, including conducting disturbance,
radioactive disturbance, conducting anti-disturbance, radioactive anti-disturbance, power falling,
mass impulse, static discharging, surge, etc. The excellent EMC characteristics can completely filter
each power grid interference, and also, decrease and eliminate the interference of UPS itself
effectively.
7 inch touch screen display
With 7 inch touch screen display, the operation is simple and convenient, which is convenient to daily
manage and maintain the UPS. It can display the running parameters and running status of UPS and
each power unit, and record the history event and alarm information. It can store 10000 pieces of
