Description

The Universal 2-Way TRIAC LED Dimmer Switch is an effective solution for controlling the brightness of dimmable LED luminaries from a single point or through a two‑way switching system. It is installed in standard 86×86 mm wall boxes and is compatible with frames from other brands such as Schneider, JUNG, Elko, or Busch‑Jaeger, ensuring perfect integration in residential and commercial projects.

TRIAC dimming: operation and recommendations

This device is based on TRIAC dimming technology with trailing‑edge phase cut. This type of dimming works by cutting the incoming sine wave signal to reduce the energy delivered to the load. This analogue principle allows brightness control but does not always provide perfect linearity, especially at startup or at very low light levels. For this reason, TRIAC dimming may not be ultra‑precise and can, in certain cases, cause flicker if the recommended minimum load is not met.

For users seeking finer, flicker‑free dimming control—particularly in professional or architectural lighting installations—it is recommended to use 0‑10 V or DALI dimming, both available in our online catalogue.

Manual brightness adjustments: minimum, maximum, and boost

This dimmer includes three integrated front potentiometers:

MIN: Allows setting the minimum brightness level to prevent flicker when dimming to very low values.

MAX: Sets the maximum brightness to limit the dimmer’s output, giving more specific control of the useful dimming range.

BOOST: Provides an initial compensation (also known as the “popcorn effect”) by giving a brief voltage surge at power‑on to ensure the luminaire starts reliably—ideal in installations with many luminaries or LEDs that require a minimum energy to ignite.

Two‑way switching operation and connection

This dimmer includes a two‑way switching function, allowing lights to be turned on or off from two different points when combined with another compatible switch. This is especially useful in hallways, bedrooms, or passage areas where control is needed from both ends.

Compatibility and connectivity

It operates directly at 230 V AC and does not require a neutral wire, simplifying installation in standard existing electrical systems. A simple yet effective solution to control lighting precisely and safely in residential environments, offices, hotels, or common areas. Adaptable, easy to install, and with manual adjustments to customise its behaviour for each project.
