This three-in single-out UPS power supply is generally used in computers that do not require three-phase electrical equipment, etc., because the three-in single-out UPS does not need to consider the load, and can steadily output continuous power even if it is out of phase. It is a very easy-to-use uninterruptible power supply. Tower UPS adopts leading online double conversion technology, with an input power factor of up to 0.9 and strong load capacity, including power 10KVA/10KW, 15KVA/15KW, 20KVA/20KW.
