Variable speed control - separate ON-OFF and light switch
SLM series are electronic fan speed controllers with a light switch. They control single-phase voltage controllable motors with a maximum current of 10 A. They control fan speed by varying the motor voltage via phase angle control - Triac technology. The minimum and maximum speed can be adjusted via internal trimmers. Kick start or soft start acceleration can be selected via a jumper.
