alternating current power

基本解释

The power supply can be 220V alternating current power supply or direct current power supply of rechargeable accumulators.
電源可以是220V交流電源或可充電蓄電池直流電源；

In a normal alternating current power system, the voltage varies sinusoidally at a specific frequency, usually 50 or 60 hertz.
在一個正常的交流電力系統，正弦電壓變化在特定的頻率，通常是50或60赫玆。
The modified types will not be equipped with commutation transformer and the three-phase alternating current power supply directly acquires DC voltage through bridge type rectifier.
改進型不配整流變壓器，將三相交流電源直接由橋式整流獲得直流電壓。
