fan speed controller

Brand Name	Telink		Place of Origin	China
Model Number	TL-SFC220

● Function The fan speed controller TL-SFC220 designed by us is an embedded one. The product through the external PWM signal or internal procedures to realize the motor speed control function. The speed adjustment including stepless speed regulation and step speed regulation. It can be a closed loop PID precise speed control method if matched with the PG signal of motor. The product through the PWM to adjust output voltage and voltage sine wave output, effectively realizes a no noise and smooth condition when motor running at a low speed. TL-SFC220 type fan speed controller designed to be embedded system has following advantages: small, light, impact resistant and strong vibration resistant, reliable, long life, easy installation. Internal electronic components using imported industrial products to assure stable performance, it can be adapted to any complex work environment. ● Application 1. Speed adjustable fan; 2.
