Description
UIM240xx Miniature Stepper Motor Controller is a series of miniature, high performance
stepper motor controller. They can be mounted onto 42 / 57 / 86 / 110 series stepper motor
seamlessly through corresponding flanges. The thickness of these controllers 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 controllers 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.
