Simple AC power short circuit protection circuit
Source: InternetPublisher:笑流年 Keywords: AC power supply short circuit protection circuit Updated: 2020/09/30
When the AC power supply voltage is normal, the relay is closed and the load (Rfz) circuit is connected . When
a short-circuit fault occurs in the load, the voltage at both ends of KA drops rapidly, KA is released, and the load circuit is cut off . At the same time, the light-emitting diode
VL lights up, indicating that a short circuit occurs in the circuit .
