High Input Power Factor, Green and Energy-Saving Power
1. The I/P power factor is above 0.98.
2. Input current THDI is less than 5%, so it greatly reduces the humornic pollution of the AC network. At the same time, the efficiency of the usage of the utility is improved so the installation cost and the noise is also reduced.
3. The speed of the fan is auto-adjustable.
4. This kind of UPS is green energy-and saves power.
