The UDK-04-10 (KNX) is a robust dimmer in leading edge and trailing edge technology. On the one hand it can be controlled by different types and on the other hand it can also control different loads:
- control via the KNX BUS system
- control of light bulbs and high-voltage halogen bulbs as well as low-voltage halogen lamps with electronic transformer
- also suitable for many types of LED retrofits
An automatic or manual switch-off function extends the application range. The UDK has 4 regulated (dimmable) outputs 230V/2.5A each with an integrated switch-on / switch-off function.
