Specification Features: Control various automation industrial equipment, flashlights, buzzers, relays, microcontrollers, or other electrical load devices. Compared with traditional device, thermal protectors and other devices, it has the advantages of high accuracy, stable performance and long service life. An ideal choice for automated industrial equipment and power monitoring. Widely used in substation, frequency conversion speed control device, inverter device, electrolytic plating, electric locomotive, street lamp monitoring, coal mine and other automation industries that need current monitoring. The current sense switch is for safety, simple, and convenient monitoring or detection of current in the electrical equipment. Using the principle of electromagnetic mutual inductance of current, the advanced output detection, monitoring and protection alarm products developed by the non-power supply technology are adopted.
