1.额定功率 POWER RATING
额定功率是指在环境温度 70℃最大输出功率,当环境温度超过 70℃时功率变化如下图:
Power rating is defined as maximum power rating continuously applied under ambient
temperature at 70℃.when the ambient temperature exceeds 70℃。
2. 额定电压 RATED VOLTAGE
额定电压为交流或直流电压(频率为 50Hz 或 60Hz)额定电压计算方式为:
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:
V = √ P×R
V = RATED VOLTAGE V 标示电压
P = RATED POWER (WATTS) P 表示功率
R = NOMINAL RESISTANCE VALUE (OHM)
R 表示阻值
When the calculated rated voltage exceeds the Maximum usable voltage flue shown
in CHART, the Maximum usable voltage is defined as the voltage According to the
power-decreasing curve shown in CHART.
