When there are bias excitation, controllable silicon failure, over current and other failures, KA5 gets absorbed and breaker loop trips by powered on so as for switching off main power supply.
KA5为跳闸报警继电器。当设备产生偏励磁、可控硅故障、过电流等故障时，KA5吸合，断路器分励线圈得电跳闸，切断主电源。
The work of switching power supply are adjusted in the on-off state, the main advantage is higher efficiency, up to 70% 95%.
开关稳压电源的调整工作在开关状态，主要的优越性就是变换效率高，可达70% 95%。
