■Advanced working mode
The dual conversion online design makes the output of UPS as a pure sine wave power supply with frequency tracking, phase locking, noise filtering and disturbance free from grid fluctuation, providing more comprehensive protection for the load.
Adopting the input power factor correction (PFC) technology, the input power factor is higher than 0.98, and the utilization rate of electric energy is improved. The harmonic pollution of UPS to the power grid is greatly eliminated, and the operation cost of UPS is reduced.
■DSPFull digital control
Using digital control, the performance index is excellent, avoiding the risk caused by the failure of the simulator, and making the control system more stable and reliable.
■Optimizing battery pack function design
Through innovationOptimizing battery pack functionThe design, both the standard and long delay type, can save the battery amount more than the traditional design under the same backup time.
■Strong environmental adaptability
Wide voltage range 115VAC ~ 295VAC, to avoid frequent changes in the grid voltage, switching to the battery power supply, adapt to the harsh environment of the power grid.
And with a minimum input voltage to 115V, without the need to switch to battery power supply.
Wide input frequency range (1-3KVA model 45 ~ 55Hz; 6KVA type can reach 40 ~ 70Hz), ensure that all kinds of fuel generator can work steadily, meet the user's requirements for the use of the oil engine.
■Support charger expansion function
- - long delay models support the charger extension, the charging current can be extended from 4A to 8A, shorten the charging time; 6KVA model 0 ~ 6A can be set flexibly to meet the needs of users.
■Comprehensive and reliable protection
It has the function of booting and self diagnosis, which can detect hidden trouble of UPS in time and nip in the bud.
It has many functions, such as AC input overvoltage protection, output overload protection, short circuit protection, inverter overheating protection, battery undervoltage warning protection and battery overcharge protection, etc., which greatly ensures the stability and reliability of the system operation.
With bypass function, when the output overload or UPS fault occurs, it can go to the bypass work state without interruption. The power supply continues to load the power supply, and provides alarm information.
The 1 ~ 3KVA model has the input zero line detection function. Can avoid the UPS city electric input zero fire line connection.
Ultra strong DC starting function.
