AC Motor Speed Controller using U2008B
- Rajkumar Sharma
This is a low cost, current feedback phase control AC motor driver based on U2008 IC. The U2008B is designed as a phase control circuit in bipolar technology. It enables load-current detection as well as mains-compensated phase control. Motor control with load-current feedback and overload protection are preferred applications.
- Supply Input: 230V AC
- Load: up to 500W (Triac Requires Heat sink for Higher Load)
- Jumper J1 Selection: A-Load Current Compensation or B-Soft Start
- PR1: Preset for Phase Control ( Ramp Current Adjustment)
- P1 : Potentiometer Set Point
