Velleman K8004 DC To Pulse Width Modulator Electronic Soldering Kit

The Velleman K8004 DC To Pulse Width Modulator Electronics Solder Kit is ideal for the accurate control of DC motors, lighting levels, small heaters as well as other applications. The K8004 circuit converts a DC voltage into a series of pulses, such that the pulse duration is directly proportional to the value of the DC voltage. The great advantage of such a circuit is that almost no power is lost in the control circuit. Protected against overload and short circuit.
