Digital Stepper Drive 1.0-3.2A 10-30VDC for Nema 17, 23 Stepper Motor
This is a digital stepper drive implemented with advanced stepper control technology. It is easy to use and it can be used to drive 2-phase and 4-phase motors(from Nema 17-Nema 23 size) smoothly with less heat and noise. It works with 10-30VDC voltage and can provide max 3.2A peak current. You can set the DIP switches to get the current and microsteps you need.

Key Features:
Anti-Resonance for optimal torque, extra smooth motion, low motor heating and noise
Motor auto-identification and parameter auto-configuration for optimal torque from wide-range motors
Step & direction (PUL/DIR) control
Multi-Stepping for smooth motor movement
Optically isolated inputs
Input voltage 10-30VDC
8 selectable micro-step resolutions of 400-12800 via DIP switches
8 selectable output current settings of 1 – 3.2A via DIP switches
Soft-start with no “jump” when powered on
Pulse input frequency up to 60 KHz
Automatic idle-current reduction
Protections for over-voltage and over-current
