Description
Introduction
The Panasonic WRKT20305NC PS132 KNX Power Supply is a high-efficiency system component engineered to provide reliable bus voltage for small to medium-sized building automation networks. Operating with a 320 mA power output on the main KNX line, it maintains consistent energy delivery across connected devices. Integrated protection mechanisms against short circuits, overloads, and input line overvoltage ensure electrical reliability and protect connected bus devices from potential power disturbances. This device is part of our KNX system devices range.
Designed for standard distribution panel installation, the WRKT20305NC features a 4-module (72 mm) DIN-rail profile and an additional unchoked 30 VDC output to power secondary non-KNX devices. Backed by official VDE certification, this unit meets international quality and safety standards. For electrical consultants, system integrators, and procurement officers, verifying exact model specifications against project BOQs ensures proper line segment planning and prevents ordering errors.
