    Key Features

    1. AC85~265V power input, design for high speed and high torque operation
    2. Max phase current to 2.0 amps.
    3. Bipolar bridge with constant current drive design to combine with a variety of 4, 6 or 8 wires 2 phase motors
    4. Selectable full-step (1.8°/s, 200s/r) or half-step (0.9°/s, 400s/r)
    5. Single/dual pulse input: (1P/2P)
    6. Adjustable driving current & holding current for the best motor rotating performance.
    7. Overheat alarm and shut down protection for safety.
    8. Built-in auto-current-down function, helps reduce motor temperature.
    9. Zero-timing output & current off function to combine external controller.
    10. Self-diagnostic.
    11. CPLD topology design to enhance stability Soft-up Current topology to prevent input power surge & spike.
    12. LED indicates rotating status.
    13. Photo-coupler I/P & O/P isolation prevents noise interference.
    14. Aluminum case extraction for heat emission
    15. Detachable terminal for easy connection
    16. SMD components for compact size
