Pulse Width Modulation (PWM) 12v DC 2a Speed Control Module.
Input from 10 to 24 volts DC, whatever voltage you input will the maximum output.
* The heat sink gives an improved tolerance of overload conditions.
An
unimpressive knob (may not be the one in the photograph) , is included,
but the 6mm spindle will accept a nice alternative.
(Hammant and Morgan knobs
fit fine).
We also list some Great Knobs.
* Simple screw wire connections.
Correct polarity is important: The underside of the pcb clearly show the correct wiring.
* Easy panel mounting using the potentiometer spindle nut. (6mm spindle)
* Don't forget - if you need Thomas to go backwards you will need to add a DPDT type switch to the output to reverse the polarity to the track.
