1. Description: This product is a smart WiFi switch with overcurrent protection, overvoltage protection, undervoltage protection, overpower protection, CPU temperature protection, but no short-circuit protection. It is recommended to use it with a circuit breaker. It complies with IEC 60947 standard 2. Applicable current occasions: AC-1, used to control circuits with pure resistive loads such as heaters, incandescent lamps, ovens, etc.; Maximum wiring capacity: power side: 10mm²; load side: 10mm²; Type: magnetic latching relay, capable of carrying large current; Pole description: 1P+N, N pole cannot be cut off 3. Real-time power monitoring (AC positive input) and management: (1) Analyze the real-time power consumption, real-time current, real-time voltage, and real-time power of the connected devices, record historical power consumption (by time, day, month, year), and export power consumption data via email. (2) Clear power consumption data (3) It has the functions of displaying the current remaining power, prepayment switch, and clearing the remaining power, which is convenient for comprehensive management of power consumption. 4. Local control: (1) Even without wifi, you can set parameters and functions through the 3 buttons on the smart wifi switch. (2) A password can be set to prevent unauthorized access and modification 5. Multiple reclosing function: There are overcurrent reclosing, overpower reclosing and overvoltage and undervoltage reclosing functions. Please note that after overcurrent/overpower protection, the device will attempt to reclose 3 times. If overcurrent/overpower persists, no reclosing will occur. After overvoltage and undervoltage protection, the device will automatically reclose. Closing threshold: overvoltage threshold -15 V, undervoltage threshold +15 V. 6. Screen display: The smart switch uses an LCD color backlight display, and the data is clear and easy to read. The brightness and directionality can be adjusted from 1 to 5 levels.
