![]() ![]() How to calculate from power ( kW & HP ) to ampere ( I )? 1) Kilo watt (kW) to ampere ( I )įor 3 phase power supply kW = I x V x 1.732 x pfįor 1 phase power supply kW = I x V x pfĮxample : 1 unit compressor size rated 37 kw,415 VAC,3 phase and 80% pf,calculate the full load ampere?įirst we must convert from hp to kW using this formula :Īfter that use the formula kW to ampere :ġ unit induction motor power rated 25 hp,200 VAC,3 phase,90 % power factor,calculated the full load ampere. We cannot get the actual full load ampere because it depend on efficiency of motor.If electric motors have a higher efficiency rating,it will draw fewer amps, for example a 10 HP motor with a 60% efficiency rating will draw about 65 amps at 230 VAC compared to about 45 amps for a motor with a 80% rating. This tool kilowatt to ampere converter can help to convert kilowatt to ampere (kw to amps calculator). Since the charge capacity (Ah) is directly related to the amount of material contained in a battery, a battery with 416 Ah would be a very large and heavy battery. Our KVA to AMPs chart allows you to see exactly what kW or voltage the given KVA rating converts to so you can safely and adequately power your generator without the worry of a power overload that could potentially damage your. Cos Power factor VL-L Phase to Phase voltage Example: For 2 kW three-phase ac supply and line voltage (Phase to phase) 415v and PF 0.9 I P (KW)1000/ 3 VL-L Cos I 21000/ 3 4150.9 5.5 A Hence 2kw 3. Then Amp-hours (Ah) energy capacity (Wh) / Voltage (V) So, you’d require a battery with: Amp-hours (Ah) 5 kWh / 12 V 416 Ah. This time i want share about how to calculated the full load ampere (FLA) of electric motor from their power rated.It not difficult if we know the right formula to get the answer.From this calculation we only can estimate the value of full load ampere. One KVA equals 1,000 volt-amps, and is calculated by multiplying voltage and amps. Generally for electric motor size,it rated by horsepower (hp) or kilowatts (kW) unit.We can recognize the electric motor size when refer to their kilowatts or horsepower.So from power (kW/hp), how we can know the full load ampere for electric motor?
