DC TO PULSE WIDTH MODULATOR (K8004)
Price: $23.90
Kit - Assembly Required
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. Can for example be used with K8000.
