DV3722 3-Phase Stepper Motor Driver 80-290VAC 4-10A

Description

The DV3722 is a DSP‑controlled, three‑phase hybrid stepper driver designed for NEMA 23–57 motors, accepting AC 80 – 290 VAC and providing 4.0 A – 10.0 A peak current (set by SW1–SW4). It delivers ultra‑smooth torque with selectable microstepping from 400 to 60,000 steps/rev via SW5–SW8, and supports both single‑pulse (PUL/DIR) and CW/CCW modes (SW9). An autorun option (SW10) enables standalone operation. Built‑in protections guard against over‑voltage, over‑current, and over‑temperature.
