ADJUSTABLE DETECTION SWITCH AC 0,2-30A Features: Control various industrial automation devices, flashlights, buzzers, relays, microcontrollers or other electrical load devices. Compared to traditional device, thermal shields and other devices, ma advantages of high accuracy, stable performance and long service life. Perfect choice of do automated industrial equipment and power monitoring. Widely used in substations, do frequency conversion speed control, inverter device, electroplating, electric locomotive, street lamp monitoring, coal mine and other automation industries that require ongoing monitoring. The current sensor switch is used do safe, simple and convenient monitoring or detection of current in electrical equipment. Using the principle of electromagnetic mutual current inductance, advanced do output detection, monitoring and protection products developed by non-power supply technology were adopted.
