Yes John it's 20-70Vac or 30-100Vdc. The AC option Just saves messing around with Bridge and Caps but still need a transformer to get from 230Vac to 20-70Vac.

Some of the Larger Nema 34's drives like these work direct from 230Vac mains. These are great for larger machines because they spin fast and have loads of torque.
