| Zusammenfassung: | The utility model discloses a safe converting circuit and temperature control system, wherein the switching circuit is connected respectively with first control ware, the second controllor, control switch, power supply circuit, and the switching circuit still is connected with actuating mechanism, when control switch was in first division of off state, power supply circuit supplied power for the switching circuit, switching circuit intercommunication first control ware and actuating mechanism, and actuating mechanism receives a controller output's signal, when control switch opened off state at the second, power supply circuit stopped for the switching circuit power supply, switching circuit intercommunication the second controllor and actuating mechanism, and actuating mechanism receivesthe signal that the second controllor exported. This scheme adopts control switch to control the mode that safe converting circuit located, and control switch is in first division of off state and offstate is opened to the se |
