Recently, I undertook a practical project using Hager and Mean Well equipment to convert a conventional LED lighting panel into a variable lighting solution. This conversion was driven by the need to adjust light intensity at night, as the client found the light excessively bright. In this article, I will describe all the steps of the project, detail the connections made, and configure the Hager domovea server, as well as provide technical specifications for the equipment used.

Building automation is constantly evolving, and the KNX protocol is one of the pillars of this transformation, being widely used for controlling and monitoring devices in smart homes and buildings. An essential component of the KNX system is the power supply, which not only provides energy but also enables communication between the devices connected to the bus. In this article, I will explain in detail how a KNX power supply works, highlighting its features and the importance of the signal generator and galvanic isolation.
