输出阻抗:阻抗是电路或设备对交流电流的阻力，输出阻抗是在出口处测得的阻抗。与模拟输出串联表示的等价阻抗。阻抗越小，驱动更大负载的能力就越高。

电击保护:当被保护线路的相线直接或通过非预期负载对大地接通，而产生非正弦波形并且其有效值是瞬时变化的剩余电流，当该电流大于一定数值时，保护器切断该线路。

Output impedance: The impedance is the resistance of a circuit or device to AC current, and the output impedance is the impedance measured at the exit. Equivalent impedance expressed in series with analog output. The smaller the impedance, the higher the ability to drive a larger load.

Electric shock protection: When the phase line of the protected line is connected to the ground directly or through an unexpected load, and the non-sinusoidal waveform is generated and its effective value is the residual current that changes instantaneously. When the current is greater than a certain value, the protector cuts off the line.
