Overview

 

UIM 24008 is a miniature, high performance stepper motor driver. It can be mounted onto 86/110mm Nema34 and Nema42 stepper motor seamless through corresponding flanges. The thickness of these driver is less than 14mm, UIM24008 is capable for 3A-8A. adjustable current output. Their mixed-decay current control reduces the back-EMF effect under high speed running condition and improves the performance. Enclosures of the UIM24008 stepper motor driver is made of die-cast aluminum which provide a rugged and durable protection and improve the heat dissipation.

 

Absolute Maximum Ratings

Supply Voltage

 

Note: Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
