== Overview ==
LCTECH single-channel AC220V 30A remote intelligent WIFI switch is equipped with the original WIFI module of well-known manufacturers, embedded in the IoT intelligent control program, only need one router with Internet access and an Android/IOS mobile phone can realize remote control of the relay anytime and anywhere, also support local buttons, 433M wireless remote control, can be used to upgrade and refit existing home appliances. Make everything smart!




== The function and characteristics ==

* Input power supply: AC90-250V, Output voltage:AC90-250V, Max output current: 30A;<br><br>

* On-board intelligent IoT WIFI module, simple configuration and powerful function<br><br>

* Support "eWeLink" mobile APP to remotely control via WIFI and 4G/3G/2G network<br><br>

* Supports timing, delay, device sharing, intelligent scene and other control methods<br><br>

* Support switch status real-time feedback when both device and APP are online<br><br>

* Support local key or 433MHz remote control, independent of WIFI/4G/3G/2G function, can control normally even when the device is offline<br><br>

* On-board 1 channel 5V, 10A/250V AC 10A/30V DC relay, can be continuously sucked 100,000 times, with diode effluent protection, short response time<br><br>
