PRSalpha

The PRSalpha line is ShopBot's most advanced control box offering powerful closed loop motors, dual emergency stop disconnect switches, and a great degree of expandability. Spindle equipped PRSalpha tools use two power sources: one for the variable frequency drive (VFD) that controls the spindle(s), and one for the control box that controls the XYZ motors. PRSalpha tools equipped with Porter Cable routers use a single power source for both router and the control box.

Note about 3 phase spindles: The Colombo and HSD spindles used on ShopBot tools are labeled for three phase power. Do not be confused by this label because the variable frequency drive (VFD) acts as a phase converter to provide the proper power to the spindle.
