NOTE: If you need assistance with circuit protection devices such as fuses or breakers, or wire sizing, please consult a licensed electrical contractor or electrician in your area who will be familiar with state and local codes.Īll information obtained while using this calculator should be confirmed by a qualified electrical contractor or engineer.Ģ. Three phase kW to Amps calculations involve a ration of 1000 times kW to the power factor times voltage and an additional factor 1. The real power P in kilowatts is equal to the power factor PF times the phase current I in amps, times the RMS voltage V in volts divided by 1000: P (kW) PF. Assumed the PF is 0.5, and supposed the voltage is 110 V, we get these result: DC: I 1000 × 9 kW / 110 V 81.82 A. AC single phase amps to kilowatts calculation formula. From our formulas follows that in order to get 9 kilowatts in amps we must know the voltage. All values should be reviewed and confirmed by an electrician or electrical engineer. Answer: the power P is equal to current of 3 amps times the voltage of 110 volts, divided by 1000. When the KVA rating has been calculated, divide that number by 0.8 to get the minimum KVA rating needed. The formula to convert amps to kilowatts for three-phase AC circuits where the current, line to line RMS voltage, and power factor is known is: P (kW) I (A) × V L-L(V) × PF × 3 / 1,000 Thus, the power P in kilowatts is equal to the current I in amps multiplied by the voltage V in volts multiplied by the power factor PF multiplied by the. * NOTE: We do not recommend loading a transformer above 80% of its KVA rating.A motor of a given rated horsepower is expected to deliver that quantity of mechanical power at the. The load voltage and load amps must be known to calculate KVA rating. First 3-phase power calculator converts kW to amps.In this case, the phase current I in amperes (A), is calculated by multiplying the real power P, in kilo-watts (kW) by 1000 and then dividing the result by the power factor multiplied by the square root of three times the line in line RMS VL-L voltage, in volts (V). Transformer capacity is rated in KVA (kilo-volt-amperes). AC three phase kilowatts to amps calculation.The equation for 3 phase current is I (Amps) 1000 x kW / (3 x VL x P.F.) where VL is the RMS value of the applied line voltage and P.F. Transformers are sized by determining the total load required (in amps). Below you will find 3 examples of a kW to Amps conversion for: 4 kW central air conditioner (220 V).The 1,000 factor is there to convert from W to kW we want the resulting power to be in kilowatts. ![]() Transformer calculator HOW TO SIZE A TRANSFORMER Basically, we just multiply amp by volts. ![]()
