This PWM controller will allow you to control the speed of DC motors up to 20A and you will also be able to control high power LEDs in Peltier cells without problems, it includes a protection fuse. A PWM regulator works from the variation of the frequency of a voltage signal, thus allowing the load to interpret a lower voltage signal. This effect can be used to control the speed of DC motors or loads that require power regulation such as Peltier cells.
