The is a robust SCR-based DC brush motor speed controller commonly used in mini lathes like the CJ0618. It typically operates on a 230VAC input and provides a variable 0–180VDC output at up to 12ADC. Wiring and Connection Guide Features a current-limiting circuit to prevent motor burnout
Ensure the heat sink has adequate airflow; enlarging the heat sink can help if running high-horsepower motors. Wiring and Connection Guide Ensure the heat sink
: Connect 230VAC (50/60Hz) to the terminals labeled AC or AC Line Input .
: Three pins for the speed control knob (typically a 5k or 10k ohm resistor).
