Motor current ratings based on kilowatt output at 120, 208, 240, 277, and 480 volts three-phase AC with an efficiency of 0.8 and a power-factor of 1. In case of the three-phase electrical generation, line to line voltage and line to neutral voltage require different constants to convert 16 kilowatts to amps, ( 3 ) and 3, respectively. Three phase kW to Amps calculations involve a ration of 1000 times kW to the power factor times voltage and an additional factor 1. of 0.9 Motor Current Ratings (Three-Phase AC) For alternating currents, the 16 kW amp transformation is different for a single phase and a 3 phase system the power factor is needed in both cases. P(W) 3 × PF × VL-L(V) The power factor of resistive impedance load is equal to 1. It means that the phase current in amps is computed by 1000. The phase current I in amps (A) is equal to the power P in watts (W), divided by square root of 3 times the power factor PF times the line to line RMS voltage VL-L in volts (V): I(A). kW (AC single phase) to Amps formula: I(A) 1000 × P(. Table 3 – Single Phase AC Kilowatts to Amps (kW to Amps) at a P.F. Calculation of AC three phase Kilowatts to amps. current I in amps (A) is equal to 1000 multiplied by (P) power in kW, divided by the voltage V in volts. Here is the table for single-phase AC Kilowatts to Amps (kW to Amps) at a power factor of 0.9 in 120 and 240 volts single-phase AC for power 1 kW to 1000 kW: Power (kW) From our formulas follows that in order to get 3 kilowatts in amps we must know the voltage. Table 2 – DC Kilowatts to Amps (kW to Amps) Single Phase AC Kilowatts to Amps (kW to Amps) at a P.F. Here is the kW to Amps Conversion Table at 110 VDC and 220 VDC for 1 kW to 1000 kW: Power (kW) Table 1 – typical power factor values kW to Amps Conversion Tables DC Kilowatts to Amps (kW to Amps) Use formulas in this chart to calculate amperes (amps), horsepower (HP), kilowatts (kW), and kilovolt-amps (kVA) for Direct Current (DC), Single Phase AC, and. 3 phase kVA to amps calculation formula Calculation with line to line voltage. Here are typical power factor values in table: Device/Loadįluorescent lighting (electronic ballast) Web10.4 Kilowatts to Amps is a tool to convert 10.4 kilowatts to amps. Conversion 1 KW 3413 BTU Load Requirement Line Current (1 Phase) Line Current (3 Phase) Applied vs. The formula states that the phase current is equal to 1000 times the power in kilowatts, divided by 3 times the power factor and the line to neutral RMS voltage. This formula relates the phase current I (in amps) to the power P (in kilowatts), power factor PF, and line to neutral RMS voltage VL-N (in volts).
