A range of Electronic Fan Speed Controllers (EFSC) designed for speed controllable single phase motors up to 10 amps peak current. The fascia is white enamelled aluminium with black knob, switch and printing. The 3 and 5 amp models are supplied with a double gang pvc-u mini trunking surface backing box with knockouts. All models have a double pole illuminated on/off rocker switch. A facility to set the minimum fan speed is standard. The 10amp model is housed in a robust die cast enclosure.


The EFSC-5(TK) is for use with fan motors with internal TK (thermal cutout) connections. The controller incorporates an on/off switch and a start button. If the motor windings overheat the TK connections open, this switches the EFSC-5 off. The start button must be pressed again to re-start the motor. A tripped indicator comes on when the TK contacts open.
