Mosttypes of three-phase power calculations are performed using this equation: P = √3 × pf × I × V This simply states that the power is the square root of three (around 1.732) multiplied by the power factor (generally between 0.85 and 1, see Resources), the current and the voltage.
Whilethey require a lot more power (480+ volts and 100+ amps), their output is truly "super." DC fast chargers can offer 50-350 kW of power; some in Europe are even reaching 400 kW.
SinglePhase 1.0 Power Factor Three Phase 0.8 Power Factor. Enter Amperes? Amps(Three Phase) = (kW x 1000) / (Volts x PF x 1.732) * Required. Clear Submit.

Note this is for AC Single Phase power. Three Phase Power runs at 400 - 415 volts . HP: Converted into Watts : 1 x HP = 746 watts: Calculate . kW: Converted into Watts : 1 x kW = 1000 watts: Air-Con Power Requirements: Amps: Convert to Watts : Starting Air Conditioner: 9.5: 2280: Running Air Conditioner: 4.2
Nomatter what voltage you use; the rated current (amps); or whether you have 1-phase power or 3-phase power; etc you can always compare watts. If you absolutely must think using amps (i.e., 3-phase power [i.e. most of EU, many other countries, and many of Raritan's largest customers in North America]—then this information does not Athree-ton central air conditioner requires between 7.5 and 12 amps, depending on the SEER. A three-ton AC with a SEER of 14 to 24 will use between 7.5 and 12.3 amps. To get the exact amps needed, you can use a simple formula. If you have a 5,000-watt air conditioner, for example, you will need 46 amps.

Theexample above (a three-phase formula) shows a generator with amps of 108 with a power of 75kVA. The kVA equates to the measure of the apparent power, but the kW is the actual power produced because KW= kVA x pf - check out our kW to kVA blog here for more info. Diesel generators typically have a power factor rating of 0.8, i.e. - pf
