Normally Open Current Sensor Switch Adjustable AC 0.2-30A SZC23-No AL-CHThe SZC23 series AC sensor switch is designed and manufactured for AC monitoring solution. It uses the principle of mutual inductance to sense the AC current, isolate the AC current, and output a normally open or normally closed switch signal to directly control various industrial automation equipment, such as flash, buzzer, relay, single-chip or other power load equipment. Compared with traditional mutual inductors, thermal protectors and other devices, the use of this device can not only achieve more accurate and timely control, but also can greatly simplify the design and reduce costs. Features: 1. Self-powered, no external power supply.2. Operating current 0.2-30A AC, adjustable by potentiometer.3. The 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 no limit on the number of opening and closing, and the response speed reaches MS.6 level. Simple structure design, insulation withstands voltage up to 2000V.7. The hysteresis is less than 1% and can be used in strong magnetic conditions.8. The outer casing is made of self-extinguishing material ABS.9. Suitable for measuring and monitoring AC current, AC motor overload protection, electronic switch of automatic control system and so on.
