The SZC23 series AC current sensor switch is designed and manufactured to solve the problem of AC current monitoring. Compared with traditional reciprocal coils, thermal protection and other equipment, the use of this device can not only get more accurate and timely inspection, but also greatly simplify the design and reduce costs. Characteristics: With its own power supply, it does not require external power supply. Operating current 0,2-30A AC, adjustable by potentiometer. The LED indicator can conveniently and intuitively indicate the operating status of the switch. Contactless electronic switch with high power MOS lamp. The switch has no limit on the number of openings and closures, and the response rate reaches ms. Simple structure design, insulation withstand voltage do 2000V. Hysteresis is less than 1% and can be used under strong magnetic conditions. The outer casing is made of self-extinguishing ABS plastic. Suitable do alternating current measurement and monitoring, AC motor overload protection, electronic automatic control system switch and so on.
