Using bipolar chopper technology,our SMD Series drivers have made L/R driver obsolete. They get your motor up to rated speed quickly and efficiently. Our popular SMD 103 driver is rated for up to 40,000 steps/second.
A 20kHz chopping rate eliminates all audible noise, and all inputs are optically isolated for noise immunity. The SMD 103 is electronically selectable between full- and half-step mode, letting you change on-the-fly without mechanical adjustments. These drivers pack a tremendous amount of power into a miniature drive. The integral heat sink helps maintain case temperature. An auxiliary heat sink (SMD 110) is required to run the driver near rated output without mounting it to a chassis.
The SMD 103 driver makes a good match with the lower current requirements of our Size 23 high-speed motors. |
