The WiFi Universal TRIAC LED Dimmer Switch is a technical solution for controlling dimmable lighting through phase‑cut technology. It is designed to be mounted in standard 86×86 mm back boxes and is compatible with standard design frames such as Schneider, JUNG, Elko, or Busch‑Jaeger, making it easy to integrate aesthetically into any residential or professional electrical installation.
WiFi connectivity and smart control
This model features built‑in WiFi connectivity through the TUYA Smart app, allowing you to manage lighting directly from your mobile phone. Using the app, available for iOS and Android, you can switch lights on or off, adjust brightness, set schedules, and create automation's based on routines or other smart‑home devices. Compatible with voice assistants such as Alexa and Google Home, this dimmer combines traditional analog control with advanced digital management from anywhere.
TRIAC technology and dimming behaviour
This device uses trailing‑edge phase‑cut technology, an analog method that adjusts light intensity by modifying the shape of the sine‑wave signal. While widely used for its simplicity and low cost, it does not provide perfectly linear dimming, especially at very low light levels. It is common for some bulbs to flicker if the minimum required load is not reached or if they are not well suited for TRIAC dimming. For projects requiring more precise and stable dimming—such as professional or architectural lighting—we recommend considering 0‑10 V or DALI‑based solutions, which are also available in our online catalogue.
In this model, the minimum load is approximately 3 W, but it is recommended to check compatibility with each luminaire. The maximum load is around 200 W for LEDs, making it suitable for most small‑ to medium‑sized residential and commercial installations. It also features built‑in protection against short circuits, overloads, and overheating, ensuring safety for both the device and the installation.
Easy installation and compatibility
It operates directly at 220 V AC and requires a neutral conductor, because the WiFi function needs constant power. A robust, connected, and easy‑to‑install option for controlling lighting intensity in homes, offices, hotels, or commercial spaces, combining traditional functionality with smart connectivity.
