kW = V × I × PF ÷ 1,000Within this model
DC or sinusoidal steady-state AC; three-phase loads must be balanced. Enter RMS values for AC and line-to-line voltage for three-phase. Three-phase output is total power across all phases. Uses true power factor; not a maximum-demand calculation.
What the numbers mean.
The result is real electrical input power. Apparent power and real power are equal only at unity power factor. A balanced three-phase calculation includes √3 and gives the total for the three phases; do not multiply the result by three again.

230 V × 10 A × 1 ÷ 1,000 = 2.3 kW for single-phase AC.
