Description
N 120/02 KNX External Bus Choke 640mA for Power Supply Unchoked Output DIN 5WG1120-1AB02
Product Overview

The N 120/02 KNX choke is a 640 mA external inductive filter designed for use with KNX power supplies that do not have an integrated choke, or for connection to the unchoked output of N 125/x2 series power supplies. It provides the current limiting and bus stabilization required for reliable KNX communication by decoupling the power supply from the bus line.

The choke features dedicated terminals for the unchoked voltage input and the choke-protected KNX bus output. As a modular installation device, it mounts directly on standard TH35 DIN rail per EN 60715 and occupies only two module widths, making it easy to add to existing panels. Using an external choke allows system designers to place power conversion and filtering functions separately, improving layout flexibility and thermal management.
