[FUNCTION]: A specially made AC current detection switch to solve the problem of AC current monitoring. It uses the principle of mutual inductance to sense AC DC current, isolate AC current, and output normally open or normally closed switching signals. [USE]: Self-powered, no external power required , the AC current detection switch has high precision, sensitive and fast response, the operating current is 0.2-30A AC, stable operation, adjustable with a potentiometer, to meet the needs of different equipment. [INTELLIGENCE]: High-power MOS tube electronic non-contact switch, which can directly control various automated industrial equipment, such as flashing lights, buzzers, relays, single-chip microcomputers or dimmers. 'other electric load equipment. [Parameters]: accuracy: 1%, offset: 1%, response time: 200ms, with LED indicator light, the current detection switch can easily and intuitive ment indicate the working status of the reverse current detection switch, and make adjustments in time. . [APPLICATION]: With strong practicability, this current sensing switch is widely used in substations, frequency conversion speed control devices, inverter devices, plating electrolytic, electric locomotives, street lamp monitoring, coal mining and other automation industries that require current monitoring.
