Digital Stepper Driver 0.3-2.2A 10-30VDC for Nema 8, 11, 14, 16, 17 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 8-Nema 17 size) smoothly with less heat and noise. It works with 10 - 30VDC voltage and can provide max 2.2A 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
