Volt – unit of measure of the electrical force or pressure which causes an electricity current to flow in a circuit.Here are some useful electrical terms related to calculating volts to watts, watts to amps, and volts to amps. In the above calculator, the installer will enter a value of 24 in the volts field and a value of 50 in the watts field.
For example a 24VAC50 power supply is 24 volt, 50 volt-amps (watts are also known as volt-amps). Typically, 24V AC power supplies have VA (voltage amps) ratings and not amps. They first need to calculate how many amps a 24V AC power supply outputs. The installer needs to calculate the distance that a power cable can be run from a security camera DVR to a CCTV camera, HD security camera, and even one of the latest UHD 4K security cameras. Here is one example of how this calculator is commonly used by security system installers as an amp calculator. The formula to convert amps to watts at a fixed voltage is: watts = amps x volts. The formula to convert volts to amps at a fixed wattage is: amps = watts / volts. The formula to convert watts to amps at a fixed voltage is amps = watts / volts. The formula to convert voltage to watts is watts = amps x volts. Click Calculate.Įxample 2: To convert watts to amps for a 12V DC 500mA power supply, enter 12 volts and. Convert / CalculateĮxample 1: To convert volts to amps for a 24V VA50 power supply, enter 24 volts and 50 Watts. This tool can convert any value as long as you enter the two other values. The calculator works by filling in any of two of the three fields (volts amps watts) to calculate the value of the third field. of 0.95.Our online calculator / conversion tool can convert watts to amps, volts to watts, and volts to amps. Three phase kilowatts to amps (kW to amps) at a P.F. Three Phase AC Kilowatts to Amps (kW to Amps).
#Amp to volt conversion calculator generator
Generator current ratings based on kilowatt output at 120 and 240 volts single phase AC with a power factor of 0.8 Single phase kilowatts to amps (kW to amps) at a P.F. Read also : power conservation ac circuit Single Phase AC Kilowatts to Amps (kW to Amps). KW to Amps Conversion Table at 110V DC and 220V DC. You can find the amps value from known kilowatts in the tables below: DC Kilowatts to Amps (kW to Amps). The amps will be:Īmps = 75.18A kW to Amps Conversion Table We have a circuit with 25kW three-phase power generator, 80% efficiency (0.8 PF) at 240volts.
To put it simply, we can get the amps from dividing the kilowatts by the product between 3, rms AC phase voltage, and power factor, then multiply it by 1000. If the phase voltage value is already known, we can calculate amps from kW using the formula below: To put it simply, we can get the amps from dividing the kilowatts by the product between √3, rms AC line voltage, and power factor, then multiply it by 1000. The amps will be:Īmps = 52.1A Three Phase AC Circuits – kilowatts (kW) to ampere (Amps) We have a circuit with 5kW power generator, 80% efficiency (0.8 PF) at 120volts. To put it simply, we can get the amps from dividing the kilowatts by the product between rms AC voltage and power factor, then multiply it by 1000. The amps will be:Īmps = 8.33A Single Phase AC Circuits – kilowatts (kW) to ampere (Amps) We have a circuit with 1kW power at 120volts. To put it simply, we can get the amps from dividing the kilowatts by voltage and multiply it by 1000.įor easier explanation, let us review the example below: We have to understand first that:įrom the previous basic power formula, we know that:ĭC Circuits – kilowatts (kW) to ampere (Amps) Besides watt and ampere, we also include voltage measurement in the conversion. We can convert watts to ampere and vice versa directly but converting kW to amps and vice versa can’t be done directly. Like stated above, kiloWatts (kW) is the measurement of the power and ampere (A) is the measurement of the current.
