WebFigure 4 is the derating output from Lambda Predict. Table 1: MIL-STD 975M derating specs for resistor, fixed carbon. Standard: MIL-STD … WebOct 20, 2010 · The formula we use to derate variable frequency drives for single phase power is as follows: AC electric motor current multiplied by 1.73, then size three phase (vfd) variable frequency drive with the corresponding amps. Most times to derate a three phase VFD for single phase power can be done by going up one size.
