Feature:1. GOOD PERFORMANCE: Variable current control technology, high current efficiency, low vibration, low speed movement, ensuring stable and reliable operation.2. STABLE CONTROL: The stepper motor driver has internal acceleration and deceleration control, greatly improves the smoothness of motor start or stop.3. PROTECTION FUNCTION: With overcurrent, overvoltage and position out of tolerance protection, the green indicates operation, the red indicates protection or offline.4. EASY TO ADJUST: Can automatically adjust the current according to the load, reduce the temperature rise, improve the motor output torsion and working speed.5. GOOD COMPATIBILITY: Digital display closed loop stepper motor driver, user can customize the number of microsteps, compatible with 1000 and 2500 line encoders.Specification:Item Type: Stepper Motor DriverVoltage Range: 24-110VDC 18-80VACModel: HBS86HContinuous Output Current: Minimum 1A, Maximum 8AInput Power Voltage: Minimum 18VAC, Typical 48VAC, Maximum 80VACLogic Input Current: Minimum 7mA, Typical 10mA, Maximum 20mAOverall Power: Maximum 200WPulse Frequency: Minimum 0kHz, Maximum 200kHzInsulation Resistance: Minimum 500MDigital Output Port Logic Current: Maximum 100mADigital Output Port Withstand Voltage: Maximum 24V.Package List:1 x Stepper Motor Driver
