UIM240xx Miniature Stepper Motor Driver is a series of miniature, high performance stepper motor driver. They can be mounted onto frame 17, 23, 34 and 42 stepper motors seamlessly through corresponding flanges. The thickness of these drivers is less than 14 mm. UIM24002 is capable to provide 0-2A adjustable current. UIM 24004 is capable for 1.6-4A adjustable current output and UIM24008 is capable for 2A-8A adjustable current output. Their mixed-decay current control reduces the back-EMF effect under high motor speed and improves the performance. Except that UIM24002 takes 10-35VDC input, UIM240xx series drivers can work on 12 to 40VDC input. Enclosure is made of die-cast aluminum which provides a rugged durable protection and improves the heat dissipation
