Finder 15.2K.8.230.0400 – 15 Series Dimmers – KNX

Why Choose the Finder 15.2K.8.230.0400 KNX Universal Dimmer?

The Finder 15.2K.8.230.0400 is a high-performance two-channel KNX universal dimmer designed for intelligent lighting control in residential, commercial and industrial building automation systems. As part of the Finder 15 Series dimmer range, this DIN rail-mounted device provides precise brightness adjustment and independent control of two lighting circuits through the internationally recognised KNX building automation protocol.

Designed for integration into KNX installations, the 15.2K.8.230.0400 combines leading-edge and trailing-edge dimming technology with programmable lighting scenarios, individual channel control and integrated electrical protection. Its flexible dimming methods allow the device to be configured for different compatible lighting technologies, including suitable dimmable LED lamps, incandescent lamps and transformer-based lighting systems.

With two independent 400 W dimming channels, a 230 V AC mains supply and a separate KNX bus interface operating at approximately 30 V DC, the Finder 15.2K.8.230.0400 is ideal for modern lighting automation projects. Its compact 70 mm DIN rail-mounted housing enables straightforward installation inside electrical distribution boards and building control panels, while ETS software configuration allows seamless integration with KNX switches, sensors, controllers and building management systems.

Intelligent KNX Lighting Control for Modern Building Automation

The Finder 15.2K.8.230.0400 KNX universal dimmer provides precise control of lighting intensity through a KNX building automation network. Unlike conventional wall-mounted dimmers, this device allows lighting circuits to be controlled through a centralised or distributed automation system, enabling integration with KNX push buttons, presence detectors, environmental sensors and programmable building controllers.

Each of the two dimming channels can be controlled independently, allowing separate lighting zones to operate at different brightness levels. This functionality is particularly useful in offices, meeting rooms, hotels, commercial buildings and residential automation installations where lighting requirements vary according to occupancy, time of day or user preference.

The selectable leading-edge and trailing-edge dimming methods provide flexibility when working with different compatible lighting loads. Leading-edge control is commonly associated with suitable conventional transformer and resistive lighting applications, while trailing-edge control is frequently used with compatible electronic transformers and dimmable LED lighting. The correct dimming method and permitted load must be selected according to the connected lamp or driver specifications.

The Finder 15.2K also supports KNX lighting scenario management, allowing predefined brightness settings to be recalled through the building automation system. Integrated thermal and short-circuit protection, individual output status LEDs and front-panel manual controls make the device a practical choice for professional electrical installers and KNX system integrators.

Configuration is performed using ETS software, enabling the dimmer to communicate with other KNX-compatible equipment and participate in wider building automation functions. Its compact DIN rail design simplifies installation within electrical control panels, making it suitable for both new KNX installations and upgrades to existing compatible systems.
