stepper motor driver with micro step

Specifications

Integrated mini stepper motor driver with microstep with parallel port(UIM240XX)

UIM24002/24004/24008 is a series of miniature, high performance PARALLEL PORT PWM Chopper Constant Current Bipolar stepper motor drivers. They can be mounted onto 42/57/60/86mm (They are NEMA17, NEMA23, NEMA24 and NEMA34 stepper motor) stepping motors seamless through corresponding flanges. The thickness of these stepper drives is less than 14mm, UIM 24002 is capable to provide 0.5-2A adjustable current output. UIM 24004 is capable for 1.6-4A adjustable current output. UIM24008 is capable for 2A-8A. Adjustable current output. Their mixed-decay current control reduces the back-EMF effect under high speed running condition and improves the performance. Except the UIM24002 takes 10-35VDC input, UIM240xx series stepper drives can work with 12 to 40VDC input...Enclosures of the UIM240xx stepper drivers are made of die-cast aluminum which provide a rugged and durable protection and improve the heat dissipation.
