DESCRIPTION
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 UIM240L02 outputs 0-2A adjustable current, the UIM 240C04 outputs1.5-4A adjustable current and
the UIM240C08 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 UIM240L02 takes 12-
28VDC input, UIM240CXX 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.
