Fuente de alimentación KNX-40E-1280D (230V / 1280mA)

It is a power supply with an output current of 1280mA (30V) with high efficiency and a compact size. It has 2 outputs, one to power the KNX bus and another additional output to power more KNX devices. With a wide temperature range from -30 to +70°C, it is suitable for all types of applications. It includes LED indicators for normal operation, bus overload, and a button to reset the rail. This -D version includes a diagnostic function, providing monitored data for better troubleshooting: output voltage, bus traffic, device temperature, and other measurement values. 

The KNX-40E-1280D source allows information to be transmitted within a standard KNX bus system, which, together with devices connected to each other via twisted pairs, allows us to monitor and control within a building, lighting, raising/lowering blinds, security systems, energy management, heating, ventilation and air conditioning systems, signaling and control systems, surface interfaces and building control systems, remote control, metering, audio/video controls, appliances, etc. The aforementioned installations and systems can be interchanged and share information; in this way, all “smart” applications in the home or in large buildings can be controlled through a very simple, integrated, and uniform control interface system.

The outputs are protected against short circuit, overload, and overvoltage. With category III overvoltage. Suitable for TP-256 and has SELV output. Version D has a bus diagnostic function.
