Startseite » Power supply units and controls
With our power supply units, you have the choice of voltage and current control. Our devices provide you with reliable performance, maximum protection and simple operation – exactly what you need for professional results.
Choose what suits your application: Constant voltage power supply units (CV) or constant current power supply units (CC), ON/OFF or dimmable.

Safe, flexibly controllable and ready for demanding applications
Our CC constant current power supply units ensure a reliable and precise supply of modern LED lighting and stand for maximum flexibility in professional applications. Thanks to integrated overload, temperature and short-circuit protection, they are particularly safe and durable, while selected variants are designed for emergency power supply in accordance with EN61347-2-13. With support for DALI, DALI Tunable White (DT8), Casambi, DMX, phase control and ON/OFF, our power supply units can be seamlessly integrated into a wide range of control concepts – the ideal solution for efficient, future-proof lighting installations.
The right basis for LED strips, modules and system integration
Our CV constant voltage power supply units provide a constant output voltage and are particularly suitable for applications with voltage-based loads such as LED strips or modules. They form a robust basis for scalable lighting systems and impress with their reliable operation and integrated protection mechanisms against overload, overtemperature and short circuit. Thanks to a wide range of control options – including DALI, CASAMBI, phase control and ON/OFF – the devices can be easily integrated into different installation and automation concepts and support the versatile implementation of modern lighting projects.

Easy integration, wireless control and convenient operation
Our independent or isolated CASAMBI built-in modules enable the convenient integration of modern, wirelessly networked lighting control in a wide range of applications. Based on Casambi technology, luminaires and components can be networked and flexibly operated without additional control cables – for example via mobile devices or external control elements. The compact design allows for unobtrusive installation, while the galvanic isolation supports safe operation. Thanks to simple configuration, the modules are suitable for both new projects and retrofit solutions and create a reliable basis for intelligent, scalable lighting concepts.
Flexible color zone control for individual lighting
With COLOUR ZONE control, different light zones can be controlled specifically and independently of each other. Ideal for LED systems with multiple color or white tones, it enables dynamic scenes, color gradients and accentuated lighting in a room or on a surface. Whether for architectural lighting, retail or event design – COLOUR ZONE ensures maximum design freedom, simple integration and precise control of individual lighting zones for an atmospheric, customizable lighting ambience.

Flexible dimming, control and scene design
Our DALI and DMX power supply units enable professional control of modern lighting systems. DALI dimmers (DT6 for single-color LEDs, DT8 for tunable white and color change) allow light intensity and color temperature to be precisely adjusted, while DMX512 dimmers offer optimum control for scenic and architectural applications in particular. Both systems support integration into intelligent building control systems, creating flexible, reliable and convenient solutions for creative lighting concepts in interiors and event areas.
