POWER RATING

power rating is defined as maximum power rating continuously applied under ambient temperature at 70℃.when the ambient temperature exceeds 70℃,use chart left.

RATED VOLTAGE

Rated voltage is defined as the DC or (AC effective Value at commercial frequency example 50 C/S, 60 C/S)

Voltage when rated power is applied and can be calculated By the following EQUATIONE=√P*R

E=RATED VOLTAGE 

P=RQTED POWER (WATTS)

R=NOMINAL RESISTANCE VALUE (OHM)

 When the calculated rated voltage exceeds the Maximum usable voltage flue shown in CHART 1,the Maximum usable voltage is defined as the voltage According to the power-decreasing curve shown in CHART above.
