PWM pulse width modulator for LED dimming for models railways hobbies 3v to 12v

Easy to use Pulse Width Modulator. In simple terms instead of using resistors to dim the led this little PCB turns the led power on and off so fast so you actually see less light. Use the dial to adjust the brightness. The dial is also on a cable so it can be used in panels etc. You could use the output to supply a string of leds (in parallel, stay under the current max). Unlike many PWM's this one is designed for lower voltages.

Overcurrent protection: Auto reset fuse will be automatically reset if needed. If this happens you likely have a short somewhere in your leds/circuit.

Input voltage is the same as the output voltage. This device does not reduce/increase voltage. 

Voltages and current:Input voltages: 1.8/3/5/6/12V DC

Current: Max 1A. DC ONLY.
