The Hartley oscillator is basically a frequency generator circuit where the oscillation frequency kind of hangs on what’s happening in a tuned circuit. That circuit involves capacitors and inductors, so […]
Heater Control Circuit with RFI Elimination and Snubber Network
This circuit is essentially a straightforward heater or light dimmer controller and it comes packed with components that help suppress radio frequency interference (RFI) and includes a snubber network. Let […]
Light Dimmer Circuit Diagram 1000 Watts
Almost every light dimmer available at typical electrical supply stores can only handle a limited amount of electricity. The power handling capacity is typically a few hundred watts. A power […]
Current Sensed Motor Dry Run Protector Circuit
Commonly dry run circuits mostly rely on water detection, which renders the designs quite antiquated and laborious. In contrast to these concept, the subsequent one relies on either load or current sensing […]
Dry Run Protection for Motor using Reed Relay Switch
When there exists no water in the tank and zero water is flowing out of the pipe plug, the pump motor could be equipped with an efficient dry run protection […]
Motor Dry Run Protection Circuit using IC4049
Six NOT gates from the IC 4049 may also be used to create a completely automatic version of a motor dry run protection circuit as seen below. This setup should operate […]
