Sonoff POWCT Power Ring WiFi Relay Module with Power Meter (100A current clamp)

Sonoff POW Ring smart power meter, also known as Sonoff POW CT, is a smart electricity meter equipped with a current transformer and a built-in relay for switching small currents (up to a maximum of 2A).

This function makes the device suitable for controlling the switching coil of a high-current contactor installed in a junction box. The measuring range of the POW CT is between 0-100A, making it ideal for measuring the main connection in apartments or houses.

As is typical of the Sonoff POW series, the device can be mounted on a DIN rail. It is equipped with a display and a micro switch for connecting to the application and switching the relay. Thanks to the external WiFi antenna, it can also be installed in a metal cabinet - the antenna simply slides out, allowing a stable connection to the WiFi router. A micro switch allows quick connection to the eWeLink app and at the same time manual control of the relay output.
