Legacy color television CRT-Based color televisionĬomputer monitor Legacy flat panel computer monitor Here in three-phase ac, we multiple power factors with √3. 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. Power factor is the ratio between real powers to apparent power.ĪC three-phase amps to kW conversion formula:Īc three-phase amps to kW conversion formula are similar to AC single phase but power factor value is changed. One KVA equals 1,000 volt-amps, and is calculated by multiplying voltage and amps. Conversion of AC single-phase we need to use power factor.ĪC single phase amps to kW conversion formula:ĪC power is equal to the current I in amps multiplied by the voltage V in volts multiplied by power factor divided by 1000. A Three-phase motor nameplate details are 5.5kW, 415 Volts Line to Line, and operated at 0.86 power factor. To convert single-phase, alternating current we use different formulas. Make a fraction of these numbers and find the final horsepower to amps value, 746 / 165.6 4.505 A. You can always convert a decimal to percent to make your life easier ( 90 0.9 ). The power rating of the motor in kW or hp. Whether its a 3-phase or single phase voltage supply. Evaluate the product in the denominator, 200 V × 0.92 × 90 165.6 V. The phase-to-phase voltage for a 3-phase supply, or the phase-to-neutral voltage for a single phase supply. To convert DC amps to kW conversion formula:ĭC power is equal to the current I in amps multiplied by the voltage V in volts divided by 1000. Estimate the power in watts (the nominator of the expression), 1 hp × 746 746 W.
