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)
