[Function]: Special AC current detection switch to solve the problem of AC current monitoring. It uses the principle of mutual inductance to induce AC and DC currents, isolate AC currents, and output normally open or normally closed switching signals. [Purpose]: Self-powered, no external power supply required. The AC current detection switch has high precision, sensitivity, and fast response. The working current is 0.2-30A AC. It operates stably and is adjustable with a potentiometer to meet different equipment needs. [Intelligent]: High-power MOS tube electronic contactless switch, which can directly control various automated industrial equipment, such as flashlights, buzzers, relays, microcontrollers or dimmers, etc. Other electrical load equipment. [Parameters]: Accuracy: 1%, offset: 1%, response time: 200ms, the current detection switch is equipped with an LED indicator light, which can conveniently and intuitively indicate the working status of the reverse current detection switch and make timely adjustments. . [Scope of application]: This current sensing switch has strong practicability and is widely used in automation industries that require current monitoring, such as substations, variable frequency speed regulation devices, inverter devices, electroplating and electrolysis, electric locomotives, street light monitoring, coal mining, etc.
