The PST2405P-2A 2-Phase Pulse Control Driver supports DC20–50V input and up to 4 A adjustable current. It features 32-bit DSP control for low-noise, low-vibration, and stable operation. One driver can synchronize two identical stepper motors (42/57 mm), with 16-level microstepping (adjustable 400–40,000 via DIP switches). Smooth, precise current control minimizes motor heating. Built-in protection against over-voltage, under-voltage, over-current, and phase errors. Serial debugging enables online parameter adjustment and monitoring. Ideal for open-loop stepper motor applications requiring dual-axis synchronized control.
