Current detection switch, current sensor, current monitoring relay, voltage regulator for automated industrial equipment, 0.2-30 A (normally open)

【Function】: This current sensor switch allows for safe, simple, and convenient monitoring or detection of current in electrical devices. Ideal for automated industrial systems and energy monitoring. 【Self-Powered】: The current sensor is self-powered without an external power supply. The operating current is 0.2 to 30 A AC, adjustable via potentiometer. This switch has no limit on the number of opening and closing cycles, and the response speed reaches MS level. 【LED Indicator】: This current monitoring relay displays the switch's operating status in a simple and intuitive way. It features a non-contact electronic switch with a high-performance MOS tube. 【Principle】: The voltage regulator uses the principle of electromagnetic current co-conductance. Advanced output protection detection, monitoring, and alarm products developed using non-electrical technology. 【Wide Application】: Our current detection switch is widely used in electrical substations, variable frequency drives, reversing devices, electroplating plants, electric locomotives, streetlight monitoring, coal mines, and other automation fields that require power monitoring.
