The Weinzierl KNX PowerSupply 365 (Art. 5335, SKU W 365) is a compact 640 mA KNX TP line supply in only 4 TE (72 mm). It includes an integrated bus choke plus a separate 30 V DC SELV auxiliary output (YE/WH). Rated current 640 mA total across KNX and auxiliary outputs. Efficiency at rated load is about 85 % (including choke); no-load loss ~1.2 W; max. ~48 W under overload.

Mains input is 230 V AC / 50 Hz. Two front buttons reset the KNX line; three multicolour LEDs show overload warning, temperature, telegram traffic and reset status. For diagnostics with OLED and logic via ETS choose 366 DGS; for integrated USB commissioning 367 USB.
