Thus, in order to measure the current I the voltage V has to be known in addition to P. In Watt’s Law, power is measured in watts and voltage is measured in volts. Convert kW to Amps From the equation in the introduction follows that I (A) 1000 × P (kW) / V (V). You can click through to FastQuote, our online quotation tool, to select.
So, through this article “ kW to Amps Calculator” we can find amperage from kilowatts if we know the voltage of the circuit using electrcial Watt’s law. that states that current = power ÷ voltage. In both BS and IEC calculations, the KW calculation is based on a power factor of 0.8. Three phase kilowatts to amps (kW to amps chart) at a P.F. Single phase kilowatts to amps (kW to amps chart) at a P.F. I=2*1000/3*230*0.9= 3.21 Amp DC kilowatts to amps (kW to amps chart) KILO WATT In the case of AC three-phase supply if watt and phase to neutral voltage is known then ampere rating can be calculated as follow :Įxample: For 2 kW three-phase ac supply and Phase voltage (Phase to neutral)= 230v and PF= 0.9
Hence 2kw= 3.09 Amp AC three phase AC three-phase supply with line to neutral voltage calculation I= P(KW)*1000/ √3* V L-L * Cosθ V L-L= line voltageĮxample: For 2 kW three-phase ac supply and line voltage (Phase to phase)= 415v and PF= 0.9 Similarly, in the case of AC three-phase supply if watt is known then ampere rating can be calculated as follow the same result can be found using above 3 phase power calculator kW to amps : Hence 2KW = 9.66 AMP single phase ac supply AC three phase kilowatts to amps calculation If for any single-phase ac circuit power kW is known then using the following formula and calculation we can easily calculate the amperage and also, we can obtain the same result from the above KW to the amps calculator.Įxample: For 2 kW single phase ac supply and voltage (phase to neutral)= 230v and PF= 0.9 Watt is the parameter to calculate how much power is consumed by a load and how much power can be delivered to a circuit. Loadhook can insure the electric chain hoist you’re seeking for your operations ensures maximum safety, efficiency, durability and economy.AC single phase kilowatts to amps calculation P(kW) 3 × PF × VL-L(V) This formula relates the phase current I (in amps) to the power P (in kilowatts), power factor PF, and line to line RMS voltage VL-L (in volts). It’s a universal method to convert kilowatt to amps. If you want to convert kW to Amps (power to current) or vice versa, you can easily use the kW to amps calculator below.
#Kw to amp conversion how to
If you are mounting the hoist to a motorized trolley, you will need to add the two horsepower values together (hoist and trolley) and then use the chart to determine the total amp draw.Īdditional items will need to be taken into consideration as your system gets more complex. We will learn how to convert 1 kW to amps (1 kilowatt to ampere). The spec sheet for the hoist will tell you the horsepower value for that hoist. An electric chain hoist uses a motor for the lifting operation. You will need to know these two values to accurately determine the amp draw based on horsepower. The below chart breaks down the values based on single phase or three phase power which would be the power supply in your area as well as standard voltages. Knowing this value is important during the design or development stage of your purchasing process because it identifies if your circuit has enough ampacity to handle the additional load of the hoist. Here we are determining the amp draw of an electric chain hoist based on the horsepower of the motors. Horsepower is a unit of power that is the rate at which work is done. Amp draw measures how much power your machine consumes during operation.
