Power in VA (apparent power) equals the product of a volt and an ampere that for direct current constitutes a measure of power equivalent to a watt. Where a reactive (capacitive or inductive) component is present in the load, the apparent power is greater than the real power as voltage an...
Volt-ampere and watt specifications in power supplies The distinction between watts and volt-amperes can cause confusion when stating power supply specifications. For example, a supply might be rated at 600 VA. This does not mean it can deliver 600 W unless the equipment is reactance-free. In ...
1 kilo-volt-ampere is equal to 1000 times 1 volt times 1 ampere: 1kVA = 1000⋅1V⋅1A kVA to volt-amps calculation The apparent power S in volt-amps (VA) is equal to 1000 times the apparent power S in kilovolt-amps (kVA): S(VA)= 1000 ×S(kVA) kVA to kW calculation The re...
