Power Calculator

These calculators will assist you in determining what size generator you may require or how to convert one unit of electricity to another. Should you have any other queries regarding our products please contact us.
 
They calculate;
Amperes when kVA is known
Converting kVA to kW
Converting kW to kVA
Converting kW to HP
kVA required to run motors
HP = Horsepower
kW = Kilo Watts
kVA = Kilo Volt Amps
I = Ampere or Current
V = Volts
PF = Power Factor
