Ambient Temperature (℃)
Power rating or current rating is in the case based on continuous full-load at ambient temperature of
70℃. For operation at ambient temperature in excess of 70℃, the load should be derated in accordance
with figure of derating Curve.
■ Voltage Rating or Current Rating
Resistance Range: ≧1Ω
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 following:
E=√P×R
E=Rated voltage(V)
P=Power rating(W)
R=Nominal resistance(Ω)
