Most switches have a standby power circuit, switching power supply in standby mode still oscillating, but the frequency of normal working hours than lower.
大多数开关电源有待机电路，在待机状态开关电源还在振荡，只是频率比正常工作时要低。
Quick and accurate fault location is the premise to rapidly isolate the fault and redelivery power supply, and it is important to the normal working of power networks.
快速、准确的故障定位是迅速隔离故障和恢复供电的前提，对于维护配电网的安全运行具有重要意义。
By monitoring both voltage and power, the unit measures the normal working load, then calculates and sets an automatic shutdown point for detected power changes.
通过监测动力电压，该装置先对正常的工作量进行测定，然后依据被测动力发生的变化，估计并设定一个自动的关闭点。
The elegant design guarantees that when the rotating device is running, the working power supply of the vibration motor is normal input and the knotting of the wires is prevented.
其中通过巧妙的设计保证当转动机构通电转动时振动马达的工作电源可正常输入，不会产生导 线打结的情况。
