Abstract

The invention refers to an electronic switching device based on the continuous monitoring of the power variation of the surveyed circuit, independent of its absolute value or frequency and represents an upgrade to the invention number 94489. The device consists of a specialized comparator (CI) on whose inputs is applied an AC measuring signal directly from the gauge and a reference signal with very fine variation obtained with the help of a special resistive divider (P2, P4 - raw; P3, P5 - fine), whose output is connected to an operating and signalling circuit (P1, LED V, OC optocoupler) respectively to the potentiometer P5. The electronic device showcases simplicity, high sensitivity, increased reliability and high noise immunity.
