420MA Adjustable Stepper Motor Driver
Product Overview
The 420MA Adjustable stepper motor driver provides configurable 4-20mA analog current-based speed control for NEMA17 and NEMA23 frame motors. Unlike the fixed-range 420MA driver, this adjustable version allows customization of the current-to-speed mapping, minimum speed, maximum speed, and acceleration characteristics to precisely match application requirements.
Operating on 12-48V DC with output current from 1.0A to 4.5A, the adjustable 420MA driver provides maximum flexibility for process control integration. The 4-20mA current-loop interface ensures excellent noise immunity for long-distance signal transmission in industrial environments.
