Amps = watts ÷ volts for DC or single-phase AC at power factor 1. For other AC loads include power factor; for balanced three-phase loads also include √3 and use line-to-line voltage. Enter electrical input watts, or select motor shaft output and supply efficiency. Watts to amps calculator Power in watts (W) Power basisElectrical input … Read more
With this tool you will know what is the equivalence of AWG (North American dimensions) to mm² (European dimensions) for cables and electrical conductors. In reality there is no exact correspondence between these two types of measurement since the specifications of both systems differ in terms of specification and resistance, however with the following application … Read more
