Velleman K8004 circuit breaker

DC TO PULSE WIDTH MODULATOR This control circuit is ideal for the accurate control of DC motors, lighting levels, small heaters as well as other applications. The 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.

- power supply: 8 to 35V DC
- maximum output current: 6.5A
- input voltage: between 2.5 and 35V DC
