1139 - DC Mini-Drill Speed Controller KIT (4-26V, 3-5A)

Stabilised power supply specially designed for controlling DC hand-held mini drills. Enables you to adjust the drill speed to suit the job at hand. Speed is not affected by the hardness of the material being drilled.

The output voltage and sensitivity are adjusted using two potentiometers. Circuit uses the well known L200 regulator IC.

Kit includes all board mounted components and solder for assembly.

PRODUCT SELECTION NOTES: The motor controller should have an output load capacity at least 25% above the motors peak power requirement. Please do NOT rely on motor rating plates for power consumption figures as they often quote average not peak power. You should verify the actual peak power at start-up and under full load before selecting an appropriate size motor controller.
