Project Box for Variable Speed DC Fan Control


I needed a small box for an installation on site for a basic DC clutch control for a Clarke clutch.

The unit was only 12vdc and 0.9A and they just needed a basic tension adjust, the original Power supply and Tension Unit would have cost in excess of £500.

£10 dc supply and £10 PWM Fan controller and £6 Display and all is well in the world again
