Meanwell KNX Diagnostic Power Supply 1280mA
The Meanwell KNX-40E-1280D is a compact and reliable power supply for KNX installations, featuring an output current of 1280 mA and an integrated choke for decoupling the bus line. This device offers a diagnostic function that continuously monitors the system voltage of the KNX installation (SELV). Thanks to the integrated overload and short-circuit protection, the installation remains safe in operation.
Using ETS software, it is possible to perform operational status and bus line analysis, enabling easy and rapid diagnosis of the system. An additional 30 V DC output is available, which is short-circuit and overload protected, and can be used to power an extra bus line in combination with an additional choke. The power supply has a wide input range of 180 to 264 V AC and is suitable for both 50 and 60 Hz power grids.
The device is designed for DIN-rail mounting (4SU MDRC) and has an IP20 protection rating, making it suitable for installation in dry indoor environments. The device status is displayed via a clear LED indicator.
