Product detailed description

📶 Sonoff WiFi Switch POW Ring

The Sonoff POW Ring smart power meter, also known as the Sonoff POW CT, is an intelligent energy meter equipped with a current transformer and a built-in relay for switching small currents (max. 2A).

Thanks to this feature, it can control the contactor coil of a high-current contactor installed in a distribution board. The measurement range of the POWCT is between 0-100A, making it suitable for measuring the main line of apartments or houses. The measurement in this case is single-phase.

The module, true to the Sonoff POW series, can be mounted on a DIN rail and comes with a display and a microswitch for pairing and relay switching. Thanks to the external WiFi antenna, it can be installed in a metal cabinet while the antenna remains outside, allowing seamless communication with your WiFi router. The device is equipped with a microswitch for pairing with the eWeLink app, and this switch can also change the state of the relay output.
