1 Multifunctional
This WIFI energy meter protector allows you to easily monitor 3 phase voltage, current, power factor, frequency and other important parameters with complete convenience.
2 Secure And Reliable
Provides a comprehensive series of conservation functions such as surge guard, under voltage guard, overload guard, under current guard, time delay guard, voltage imbalance guard, current imbalance guard, and phase loss guard.
3 Quick Response
Guards against overvoltage, undervoltage, or overcurrent conditions by immediately interrupting the power supply to prevent damage. Automatically turns on again once voltage normalizes.
4 Backlight LCD Display
Features a clear display for easy viewing in low-light environments, with a backlight that automatically turns white when the guard is functioning properly.
5 Sturdy And Robust
Manufactured from premium flame-retardant PC and high-conductivity red copper materials for enhanced durability, abrasion resistance, and extended operational life.
Ideal for factories, workshops, and assembly lines to monitor and optimize power consumption of heavy industrial equipment.
Designed for office towers, shopping malls, and hospitality centers requiring individual unit sub-metering and smart energy management.
Applied across hospitals, schools, and transportation hubs to ensure continuous, highly stable power distribution for critical equipment.
Optimized for solar generation plants and EV charging infrastructure to achieve bidirectional measurement and automated load balancing.
If your working voltage is 110 VAC, the device may trigger undervoltage protection automatically upon first use. Simply enter the settings via the screen or mobile app to calibrate the overvoltage and undervoltage parameters to suit your grid standard.
The device supports standard Tuya and Smart Life mobile apps for continuous remote control and parameter setting. It also supports voice control through Amazon Alexa and Google Assistant.
Yes, once the voltage, current, or related circuit conditions normalize, the protector completes the preset guard delay cycle and automatically restores power safely to connected loads.
The device is engineered for standard 35mm DIN-rail enclosures and accepts copper wire connections up to 35 square millimeters.
Yes, the overcurrent limit can be set from 1A to 100A, and action delay settings are fully configurable between 0000 and 9999 seconds to meet specific load demands.
