What power supply do the cabinets require?

The cabinets auto-sense mains voltage and accept AC 110 V or 220 V at 50 or 60 Hz, so the same unit works on either supply without a step-down transformer or an internal change. Power draw is modest and depends on capacity and grade — a 100 L grade A cabinet draws 10 W, while the largest 1430 L grade C cabinet draws 78 W. The figure for each model is listed in the specification table. The ovens are different: models up to 240 L run on single-phase AC 220 V, and from 420 L upward on three-phase AC 380 V.
