City Power ⇆ Generator/PVWIFI smart dual power switch by TUYA/SmartLifeGeneral  TOQ7S is a WIFI-enabled smart ATS that can be controlled via TUYA/SmartLife. This device supports various functions such as remote power switching, countdown, Timer, relay status, etc. This device is an upgraded version of the TOQ7e series. The key improvement lies in the fact that the status of the APP will not change with the switching of the power supply.When you select ON (Source A) on the APP, TOQ7S will operate as a normal ATS. After source A loses power, the equipment automatically switches to source B. After Source A is restored, it will automatically switch back to Source A.When the power of source A is cut off, the TOQ7e will automatically switch to source B. At the same time, the APP will also switch to source B. The device will not switch back to source A.These two devices will not automatically switch back to source A even after you select source B on the APP, regardless of whether source B is powered or not.You can choose the suitable products according to your needs. Product ParameterRated supply voltage Us: AC (L N) 220V-230V 50Hz-60HzWorking condition: 85% Us~110% UsSwitching time: <50msAction time: <50msRated impulse withstand voltage (kV):8kVElectrical Life: 2000 timesMechanical Life: 5000 timesNoted: 1.The product works with L+N 220-230V 50-60Hz.2.The WIFI chip is powered by source A.
