MEAN WELL, the leading standard power supply manufacturer, continues to promote the building automation technology for making a green and sustainable society. KNX switching actuators play an essential role in building automation and they are responsible for the reliable switching of different electrical loads in the KNX system. After the launch of KAA-8R 8 channel actuator device, the new KNX 4 channel dimming actuator is proudly introduced.
 
The KAA-4R4V dimming actuator is a 4 channels device with high-quality independent latching relay to turn on or off, which is suitable for MEANWELL all kinds of LED drivers. The product specification indicates the maximum number of recommended LED drivers per channel which is easy for building planning.

Based on the KNX architecture, KNX system engineers can easily program through the ETS system as needed during planning or use, or manually through the physical buttons on the panel. The KAA-4R4V dimming actuator is independently configured with a green LED indicator on each channel to indicate the status of the switch. The compact design with 4 units(72mm) wide modular makes it suitable for installation in the distribution board on 35mm mounting rails in the EIB/KNX application. In addition to the basic switch function, a DC 0(1)-10V signal to perform the dimming on the connected driver at each channel. The dimming curve can be adjusted to linear or logarithmic mode so that the end user has excellent dimming experience. It can also be used with motion sensors in the buildings to save energy. The dimmer is powered via the EIB/KNX and does not require any additional power supply. As result, KAA-4R4V is featuring both reliability and multi-functionality to meet various needs in a modern building.
