Precise motor speed control The controller provides fine control over motor speed with a duty cycle adjustable from 0% to 100%, allowing you to set exact speeds for different loads and tasks. Wide voltage compatibility Input voltage range is 8V to 12V, enabling use with a variety of DC power sources such as batteries and DC power supplies. This flexibility helps fit the controller into different projects and layouts. Overcurrent protection with self restoration Builtin self restoring fuse protects against excessive current. It automatically disconnects if the current exceeds the 2A limit and resumes operation after cooling, helping to maintain safety and reduce downtime. Suitable applications and limitations Designed for use with DC power supplies and motors with a continuous current greater than 5A. Not recommended for power motors or for use with household 220V AC power. Use scenarios Mobile robot drive: Pair with an 812V battery to drive a DC motor with continuous current above 5A. You can dial in smooth acceleration and precise speed for reliable navigation. Small automation line: Control a DC motor in a compact conveyor or feeder system. The overcurrent protection helps prevent stalls and electrical faults, supporting safer startup and operation. Electronics enclosure cooling: Drive a DC cooling fan, adjusting speed to maintain temperature targets without overloading the motor or power supply.
