The Weinzierl KNX PowerSupply USB 367 (Art. 5219, SKU W 367) combines a 640 mA KNX line supply, diagnosis node and a galvanically isolated USB programming interface in 4 TE. Bus and auxiliary outputs are 30 V DC SELV with 640 mA shared rating; mains 230 V AC / 50 Hz; ~85 % efficiency.

USB uses HID/cEMI (System B, max. APDU 55 on this interface) via a USB 2.0 Micro-B connector and is supported by ETS 4.2+ and visualisation tools. The KNX node monitors current, bus voltage and temperature; an OLED with four buttons shows parameters locally. Compared with a separate 312.1 plus 365, the 367 saves rail space in small boards. For diagnosis without USB see 366 DGS.

Key Features — 367 USB

Choosing and Commissioning

Note the USB interface APDU length (55) vs Long-Frame interfaces like 312.1 when Secure/long downloads matter — pick the right tool for the job. Mains install needs disconnect + 16 A fuse. Downloads include datasheet, manual, ETS zip, CAD and CE.
