The Weinzierl KNX PowerSupply DGS 366 (Art. 5207, SKU W 366) is a 640 mA KNX bus supply with integrated KNX node, diagnosis and logic — still only 4 TE. Like the 365 it provides a choke, KNX 30 V SELV output and auxiliary 30 V SELV (shared 640 mA rating), ~85 % efficiency and 230 V AC input.

The onboard node monitors output current, bus voltage and enclosure temperature. Logic functions are available in the ETS application (ETS 4.2+). A front OLED display with four buttons shows operating parameters locally, plus a KNX programming button/LED. Choose the simpler 365 without diagnosis UI, or 367 when USB bus access must sit in the same 4 TE block.
