| The following information
is provided by Electro-light: In a
continuing effort to improve our product, the MC-12 now has a larger
heatsink for cooler operating temperatures and increased reliability.
This circuit is designed to control the speed of a brushed
DC motor with a potentiometer that adjusts the duty ratio from 0% to 100%.
The control method is pulse-width-modulation (PWM).
The circuit is intended for 12 volt systems but will
operate from a 6 - 15 VDC supply.
The output current is rated at 20 amperes
continuous!
Suitable for electric bicycles, electric scooters,
electric vehicles, and lighting and heating control.
Our customers have also found the MC-12 useful for HHO
generation and hydrogen boosting!
Specifications:
Supply/Motor Voltage: 6 - 15 VDC
Output Current: 0 - 20 amperes continuous
PWM switching frequency: 1250 hz - 120,000 Hz
(continuously adjustable)

(1) MOSFET Mounting Hardware (#M-3 machine screw, lock washer, shoulder
washer, and TO-220 insulator).
(1) Complete circuit schematic with wiring diagram and assembly/soldering
instructions.
User Requirements:
- Wiring, assembly, and soldering skills
- A 12 volt battery or dc power supply
- 10 - 12 gauge hook-up wire between the power supply, motor, and PWM.
