2.1.2 Features
Completely digitalized smart control
The UPS support various input and output mode, such as 33/31 and 11 (just for 10-20k) 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.
Low mains input voltage
Adopt the independent rapid detection technology. When output load is small, even the battery
voltage is 80V, which is the mains low limit, the battery still doesn't discharge. Therefore, in the
mains mode, all output power gets from the grid, which is to ensure the battery in 100% energy
storage status, and at the same time, reduce the battery discharge times and prolong the service life.
