NEW ARRIVAL Tuya Smart Energy Meter with Clamp 80A
Please note it’s not bidirectional meter, it can only measure the consumed power. and only show positive data on App.
The meter requires the measured device must have neutral wire. otherwise it can’t measure the device’s voltage, current, and power
In the APP It Can Display:
Hourly Elec. (KWh)
Today Elec. (KWh),
Monthly Elec. (KWh)
Yearly Elec. (KWh)
Rated Voltage:100-240V AC 50/60Hz
Measurable Current Range: 0.2A – 80A
Ambient Temperature Range:-10°C ~ 55°C
App Real Time Monitor Energy Consumed KWh. Voltage, Current, and Power, also can Monitor Device Working Status
You can view hourly , daily , monthly, Yearly and total KWh Consumed . in App
Monitor Power Usage Percentage from App
You can set power on App, and monitor the power usage percentage
Monitor Device Working Status
Automation , It allows to make a Scene for this device working with other tuya devices
Set Automation for the Measured Device ,
For example, If Power or Current Is over the Value, then other tuya device starts to work .
Automation. It allows to make a scene when the device turn off, send a notification
Easy and Safe to Install
Non-Connect to be safe.
No need to change your wire connection, just put the wire into the clamp, then it can measure.
Small Size Module , Easy to Install
We guarantee good quality, every product will be tested before delivery. Not before Order
Q : After I configure it with App , why App shows ‘shutdown’ ?
A : Only if you put a device’s wire (either live wire or neutral wire, not both) in the clamp, and turn on the device, then the clamp can sense the current, and App will show it is working
Q : I suppose P= U*I, why the value shows on App is not correct ?
A : Please consider the cos(Φ).
Because As resistances do not produce any phasor difference (phase shift) between voltage and current waveforms, all the useful power is delivered directly to the resistance and converted to heat, light and work. Then the power consumed by a resistance is real power which is fundamentally the circuits average power.
To find the corresponding value of the real power the rms voltage and current values are multiplied by the cosine of the phase angle, Φ as shown.
Real Power P = I2R = V*I*cos(Φ) Watts, (W)
