- Designed for unstabilized motor supply voltage
- Alarm output or pre-alarm output
- Half-step and full-step mode
- Built-in protection diodes
- Bipolar drive of stepper motor for maximum motor performance
- Wide voltage range 10 to 50 V
- Thermal overload protection
- Wide range of current control 5 to 1500 mA
