Please note that this TUYA wifi energy meter will update the Kwh data when disconnected from wifi, other types of Metering circuit breakers will not increase the Kwh when disconnected from wifi.
Please note this meter only can remotely measure the Kwh voltage, current, and active power, and doesn't have a timer or remote on/off function.
1. Total active energy kWh measure
2. APP can read kWh, R.M.S current, voltage, active power
3. LCD display, Real-time display of Voltage, Current, Active Power, Reactive Power, power factor, frequency, total Energy kWh
4. Power Supply: 110V+110V+N, Please note this meter for Brazi, USA. 2 phase 3 wires.
5. MAX Current: 100A Clamp CT
6. Pulse Frequency: 1000imp/kWh
7. 35mm Din Rail install
8. Active energy accuracy is class 1, IEC62053-21
Push the button for more than 10, the WIFI LED will flash quickly, use the APP to operate
bear 400V /hour, not damaged
Note: This meter Only supports 2.4G Wireless Network, NOT for 5G
The meter is designed to measure single-phase-three-wire AC active energy and variable parameters like residential, utility, and industrial applications in South America or North America. It can remotely read from WIFI communication. It is a long-life meter with the advantage of high stability, high overload capability, low power loss, and small volume.
Basic Function
★LCD display, button for LCD display step-by-step
★Bi-directional total active energy, reverse active energy measure in the total energy
★The meter also displays real conjunction phase voltage, conjunction phase active power, L1 line current, frequency
★history active energy consumption tracking by APP
★check the real conjunction phase voltage, conjunction phase active power, and L1 line current by APP
★Clamp CT connection, easy for installation
★Pulse LED indicates the working of meter
★Energy data can be stored in a memory chip for more than 15 years after powering off
★Active energy will be kept in the meter memory chip when the WIFI connection fails. it will not lose and will upgrade after the WIFI connection again
★18mm width only 1 pole MCB dimension, 35mm din rail installation
