3535O - DC Full/Half Step Drive w/ Oscillator

The 3535O is no longer available. Consider the ST5-S as a replacement.

The 3535O step motor drive is a full or half step drive for use with 2-phase stepper motors. It can operate in either step & direction mode or oscillator mode (jumper selectable). The 3535O utilizes three-state switching amplifiers and opto-isolated input circuits. The 3535O 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 3535O 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.
