Whether the regular residences or the commercial office buildings, in order to make the management of the architectural complex more convenient, safer, and more energy-saving and avoid exploiting excessive wiring to collocate the intelligent sensor and detection devices which lower the cost of the wiring and the difficulty of installation so as to lessen the maintenance fees of the whole system and the risk of accidents, the only one worldwide standard for home and building control field- KNX- is utilized all over the world to transfer control data to all building management components to ensure that all components communicate via one common language and employ a system to deal with the problems of device isolation.

MEAN WELL, the world-famous standard power supply leading manufacturer in industrial control field, has actively participated in intelligent-control related field and is now pleased to officially unveil the first 20W KNX power supply ~ KNX-20E series to fulfill the demands for standard KNX power supply from the intelligent building market. This product is able to drive the standard KNX bus system, and the devices on KNX bus are able to be connected by the KNX twisted pairs, that it is very suitable for the monitor and control, within buildings, for lighting, blinds / shutters, security systems, energy management, heating, ventilation and air-conditioning systems, signaling and monitoring systems, surface interfaces and building control systems, remote control, metering, audio / video control, white goods, etc. The aforementioned facilities and systems can interchange and cope with the information; all of the intelligent applications in home or the buildings can thus be controlled through merely an integrated uniform control interface system.
