Power Derating Curve

Power rating or current rating is in the case based on continuous full-load at ambient

temperature of 70ºC. For operation at ambient temperature in excess of 70ºC, the load

should be derated in accordance with figure of derating Curve.

Rated Voltage: The resistor shall have a DC continuous working voltage or a RMS AC

continuous working voltage at commercial-line frequency and wave form

corresponding to the power rating, as determined formula as follows:

E = Rated Voltage (V)

P = Power Rating (W)

R = Nominal Resistance (Ω)

E = √P x R
