KNX Lighting Control

Lighting systems must not only strive to achieve energy-saving, environmentally-friendly, and high efficiency, but being comfortable, flexible, and human-oriented. With the development of information network technology, the KNX bus technology is becoming more and more mature, which has promoted the development of the intelligent building industry. Under these preconditions, the concept of "intelligent lighting control system" emerged.

The architecture of the system consists of a power supply that supplies the KNX bus. The KNX switch actuator is used to control the LED driver. If dimming function is required, an optional dimming switch actuator with a dimmable LED driver is expected. To meet the above application demands, MEAN WELL developed KNX bus power supply “KNX-20E” and “KNX-40E”. KNX universal actuator has “KAA-8R”. KNX LED actuator/dimmer has “KAA-4R4V”. Regard to LED drivers, MEAN WELL has developed a variety of products, so customers could refer to MEAN WELL LED driver solutions.

Mean Well KNX solutions for smart building automation

Mean Well is offering KNX global open standard solution for smart building automation. Mean Well KNX devices have different functions for every project. They are able to manage remote control unts with LED lighting, display, shutters and Heating Ventilation Air Conditioning. Also security systems, energy management, audio and video equipment can be remotely controlled with KNX.

KNX-40E 1280 mA KNX Power supply

The KNX Power Supply KNX-40E-1280 is a 1280 mA power supply with high efficiency and a small footprint of only 4SU (72 mm). The device has a KNX bus choke output and additional output for auxiliary power. The -30~+70°C wide temperature operating range can meet all kinds of applications. LED indicators are used in case of normal operation, overload conditions and RESET operation. It is perfectly suitable to power up any products labeled with the KNX trademark. With over 30 years of industrial power supply experience, KNX-40E-1280 is engineered to be a reliable and safe solution for the KNX bus environment.

Mean Well KAA-4R4V

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 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.

Mean Well KSR-01IP

The IP TP media coupler KSR-01IP is a KNXnet/IP routing & tunneling device and works as KNX IP line/area coupler. No need to have an external power supply for powering. The ability to address all bus devices in the KNX bus system makes network operations less time-consuming. Operational and filtering states, malfunction and faulty communication are indicated by LEDs. The device supports UPnP and its firmware can be updated via the built-in web front-end page provided an easy IP communication interface for systems or devices that use KNX building automation control technology.

Mean Well KSI-01U

KSI-01U is an interface for establishing a bidirectional connection between a PC and the KNX installation bus. The USB connector has a galvanic separation from the KNX bus. It can be used on the standard software like ETS, EITT (also Raw Frame operating mode) and other software is handled by the FALCON driver. The KSI-01U supports long messages (up to 220 byte APDU length) and ensures easy handling in software under operating systems not supported by the FALCON driver (e.g. Linux), providing an easy communication interface for systems or devices that use KNX building automation control technology.
