ADM42H / UIM42H Stepper Motor Driver
Product Link
[edit]Description
[edit]The ADM42H (UIM42H) is a compact pulse and direction stepper motor driver with spontaneous pulse capability. Measuring 42mm x 42mm x 21.5mm, it is designed for NEMA17 stepper motors.
This driver supports both standard pulse and direction control and spontaneous pulse (standalone) modes. In spontaneous pulse mode, the motor rotates instantly when power is applied, with speed configurable via DIP switches. It uses a 32-bit digital chip with advanced control algorithms.
The driver operates on 12-40VDC with 24VDC recommended. Continuous output current is 1.4A with 2.1A peak. Protection includes over-voltage, under-voltage, and over-current protection with automatic motor parameter matching.
