Features
Completely digitalized smart control
The UPS support various input and output mode, such as 33/31 and 11 (just for IST7 series
10kVA-20kVA) mode UPS. The UPS can monitor the grid frequency (50Hz/60Hz) and self-
adapt the frequency. The output voltage can be set to 220V/230V/240V, which makes the use
more flexible.
Energy conservation and high efficiency
Adopts three-level inverter technology and PFC control technology, the output voltage wave
is perfect and the whole efficiency can be 96%, 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.
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 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, which guarantee the reliability of power supply
and also, save energy.
