This circuit interrupts the power supply when grounding is missing. The circuit is from an old documentation (from the 80's) using current transformers and other components of the time.
This circuit uses a general-purpose transistor and has waveform adjustment. We found it in an...
This 1 kW circuit was found in documentation from the 90s. The sensor is a thermistor, and the...
