    Power Supply Calculations

    Hi, 15Amps at 13.8VDC = 207W 90% efficiency....power on AC side = 230W P = V*I*pf 230 = 240*I*0.95 I = 1.009A??? Would this we the correct answer? Sorry Macgyver, this was a discussion I was having with a friend and thought we would get a confirmation. Thankyou for your responses

    Power Supply Calculations

    Hi, If you have a Power supply, that supplies a load of 15Amps at 13.8VDC, how would you calculate the current on the AC side of the supply (@240V). (this information could help with circuit breaker sizing etc?) If you have to assume an efficiency for the power supply and a input power factor...

    Power Output of a generator

    Thankyou very much. Is there a formula to use for three phase that can make this calculation quicker? For example 26.4Amps total. What equation can be used to calculate Total KVA? Cam

    Power Output of a generator

    Hi Guys, A basic question about output power from a generator: If I have a three phase generator supplying: Red 10.5A White 6.4A Blue 9.5A ..and I take (240v*10.5)+(240v*6.4A)+(240v*9.5A) will this give me total power output in KW or in KVA? And then how does one get the other format...
