This is a 1280mA (30V) power supply with high efficiency and a compact size (4SU-72mm). It has two outputs: one to power the KNX bus and an additional output to power more KNX devices. With a wide operating temperature range of -30°C to +70°C, it is suitable for a variety of applications. This –D version includes a diagnostic function, providing monitored data for improved troubleshooting: output voltage, output current, bus traffic, device temperature, and other measured values. It also features LED indicators for normal operation, bus overload, and a button to reset the bus rail.
The KNX-40E-1280 power supply enables the transmission of information within a standard KNX bus system. This, along with interconnected devices using twisted pairs, allows for the monitoring and control of various systems within a building, including lighting, blinds/shades, security systems, energy management, heating, ventilation and air conditioning, signaling and control systems, surface interfaces, building control systems, remote control, metering, audio/video controls, household appliances, and more. The aforementioned installations and systems can exchange and manage information, enabling all "smart" applications in homes or large buildings to be controlled through a simple, integrated, and uniform control interface system.
