The N 125/12 KNX power supply unit provides a regulated DC 29 V output at 320 mA, making it ideal for medium-sized KNX bus segments with a moderate to high device count. It installs on standard TH35 DIN rail per EN 60715 in a compact four-module-width enclosure. The integrated chokes protect the bus from current spikes and maintain reliable communication, while the additional unchoked DC 29 V output enables a second bus line to be powered via an external choke such as the N 120/02.
