1·The LED fixture shall be operated at constant and carefully regulated current levels. LEDS shall not be overdriven beyond their specified nominal voltage and current.

LED灯具须在稳定的、精心调控的电流强度下运行，不应在超过其额定电压或额定电流的情况下超负荷运行。

2·The NiZn cell has a nominal voltage of 1.65V, which is 30% higher than that of a NiMH cell (1.25V nominal). When freshly charged, its terminal voltage is even higher at 1.85V!

镍锌充电电池正常工作电压是1.65V，比常规的镍氢电池的1.25V高出30%。当刚充完时，两个端极的电压甚至能高达1.85V！

3·Undershoot Undershoot refers to the amount by which voltage or frequency drops below the nominal value as the voltage regulator or governor responds to changes in load.

下超调下超调指电压调整器或控制器在应对负荷变化时，电压或频率低于额定的量。

4·Undervoltage Sensing for Each Phase of Normal Source: pickup voltage is adjustable form 85 to 100 percent of nominal, and dropout voltage is adjustable from 75 to 98 percent of pickup value.

正常源每一相位的欠压传感：起始电压可在额定值85 - 100%的范围内调节；回动电压可在始动值75 - 98%的范围内调节。
