UIM240XX Miniature Stepper Motor Drivers are series miniature, high performance stepper motor
controllers.

They can be mounted onto NEMA 17 / 23 / 34 / 42 series stepper motor seamlessly
through corresponding flanges. The thickness of these controllers is less than 15 mm.

The UIM24002 outputs 0-2A adjustable current, the UIM 24004 outputs1.5-4A adjustable current and
the UIM24008 outputs 3-8A adjustable current. 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 work on 12 - 40VDC input.

The enclosure is made of die-cast aluminum which provides a rugged, durable protection and improves
the heat dissipation.
