3535 - DC Full/Half Step Drive

The 3535 is no longer available. Consider the STR2 or STR4 as a replacement.

The 3535 step motor drive is a full or half step drive for use with 2-phase stepper motors in step & direction applications. The 3535 utilizes three-state switching amplifiers and opto-isolated input circuits. The 3535 also includes an automatic idle current reduction feature that lowers motor current by 50% anytime the motor is left at rest for more than one second.

The 3535 amplifier regulates motor current by chopping at a constant, inaudible frequency. Phase current is selected from 16 levels by a DIP switch. Full or half step resolution is also switch selectable.
