What is the meaning of kva in UPS power supply?
Ups in the K is the UPS can output the actual power, and VA refers to the UPS's actual power is only 70 percent of the VA, for example; 1KW 24VDC refers to the UPS can output the actual power of 1KW, DC input 24V The 1KVA 24VDC means that the UPS can output the actual power of 1KW x 70% = 700W, DC input for the 24V, professional UPS,
In addition to the apparent power, the alternating current also has active power and reactive power, the relationship between the three is: the square of the active power plus the square of the reactive power is equal to the square of the apparent power.
KVA read as "kVA", it is the unit of apparent power of alternating current, 1kVA = 1 000VA. For UPS, this parameter is basically the rated output power of the UPS (apparent power). A more common power unit in life is W (Watt), which is the unit of active power.
