Published:2009/7/9 23:39:00 Author:May | From:SeekIC

Deleclor circuit with high sensitivity and stability, followed by audio ampliler, serves as differential voltage or current alarm. Input may be d-c or low-frequency a-c. Output is distinctive series of audio beeps or continuous tone, occurring only when preselected polarity unbalance is present at input.-C. E. Miller, Differentktl-Voltage or Current Alarm Circuit, EEE, 12:7, p 25.
