- Power derating curve
Power derating curve
(1)Rated power:
Standard ambient temperature is 30℃. If ambient temp. is over 30℃,
calculate the maximum power by multiplying rated power with the designated ratio from the derating curve.
(2)Rated power:
E=√R×P
E:rated voltage(V)
P:rated power(W)
R:Rated resistance(Ohms)
The rated voltage is the corresponding voltage of DC or AC (impedance of the commercially used frequency) based on the formula above.

Derating curve(RL7520W)
Rated current
The current that causes 20℃ temperature increase by impedance.
If the ambient temperature exceeds 70℃, reduce the current according to the derating curve below.
Power = (current)2 x DC Resistance of the product
