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