A

DC Kilowatts to Amps calculation

The current I in amps (A) is equal to 1000 times the power P in kilowatts (kW) divided by the voltage V in volts (V):

I(A) = 1000 * P(kW) / V(V) / 1000


AC Single Phase Kilowatts to Amps calculation

The phase current I in amps (A) is equal to 1000 times the power P in kilowatts (kW) divided by the power factor PF times the RMS voltage V in volts (V):

I(A) = 1000 * P(kW)) / (PF * V(V))


AC Three Phase Kilowatts to Amps calculation

Calculation with line to line voltage

The phase current I in amps (A) is equal to 1000 times the power P in kilowatts (kW) divided by the square root of 3 times the power factor PF times the line to line RMS voltage VL-L in volts (V):

I(A) = 1000 * P(kW) / (√3 * PF * VL-L(V))

Calculation with line to neutral voltage

The phase current I in amps (A) is equal to 1000 times the power P in kilowatts (kW) divided by 3 times the power factor PF times the line to neutral RMS voltage VL-N in volts (V):

I(A) = 1000 * P(kW) / (3 * PF * VL-N(V))
