Current Sensing Switch Switch Type: Sensor Switch Item Type: Switches SZC23 series AC current sensing switch is designed and manufactured to solve the AC current monitoring. It uses the principle of mutual inductance to sense the AC straight-through current, isolate the AC current, and output a normally open or normally closed switching signal to directly control various automation industrial equipment, such as flash, buzzer, relay, single-chip or other power load equipment. Compared with traditional mutual inductors, thermal protectors and other devices, using this device can not only accurate and more timely control, but can also greatly simplify the design and reduce costs. Model Number: SZC23-NO-AL-CH Current Sensing Switch 1. Self-powered, no external power supply required. 2. Action current 0.2-30A AC, adjustable with a potentiometer. 3. LED indicator can conveniently and intuitively indicate the working status of the switch. 4. High-power MOS tube contactless electronic switch. 5. The switch has on the number of opening and closing, and the reaction speed reaches the ms level. 6. Straight-through structure design, isolation withstand voltage up to 2000V. 7. Hysteresis is less than 1% and can be used under strong magnetic conditions. Suitable for AC current measurement and monitoring, AC motor overload protection, electronic switch of automatic control system and so on.
