These Solid State AC Variable Voltage Fan Controls operate from 115/230 Vac, 50/60 Hz and are designed to replace obsolete tapped windings, chokes, rheostats, and other methods, which are currently being used to obtain speed variations. The controls are available with an internal on/off line switch and are also available with an optional third lead, which can be used to control auxiliary circuits such as relays dampers or louvres and indicator lamps. A wall mounting kit is available which includes dial plate, knob, mounting strap, hardware, and instructions.
