N 125/22 KNX DIN Rail Power Supply DC 29V 640mA High Current Line Plus Choke 5WG1125-1AB22

The N 125/22 KNX power supply unit delivers a high-capacity regulated DC 29 V output at 640 mA, designed for large KNX installations with many bus-powered devices. It mounts on standard TH35 DIN rail per EN 60715 and integrates chokes to protect the bus and stabilize communication during switching events.

The additional unchoked DC 29 V output can feed a second KNX line through an external choke such as the N 120/02, supporting centralized power with distributed line topology. For very large systems, multiple N 125/22 units can be operated in parallel to scale current capacity.

The wide input voltage range accepts AC 120 to 230 V at 50/60 Hz or DC 220 V, making the unit suitable for global projects. LED indicators and clearly marked terminals simplify installation and diagnostics.
