SZC23 series AC current sensing switch is designed and manufactured to solve AC current monitoring.
It uses the principle of mutual inductance to detect AC through current, isolate AC current, and output normally open or normally closed switch signals to directly control various automated industrial equipment, such as flashlights, buzzers, relays, microcontrollers or other power load devices.
Compared with traditional transformers, thermal protectors and other devices, the use of this device can not only obtain more accurate and timely control, but also greatly simplify the design and reduce costs.
1. Self-powered, no external power supply required.
2. The operating current is 0.2-30A AC, which can be adjusted by a potentiometer.
3. The LED indicator can conveniently and intuitively indicate the working status of the switch.
4. High-power MOS tube non-contact electronic switch.
5. The number of opening and closing of the switch is unlimited, and the response speed reaches the ms level.
6. Straight-through structure design, isolation withstand voltage up to 2000V.
7. The hysteresis is less than 1% and can be used under strong magnetic conditions.
8. The shell is made of self-extinguishing material ABS.
9. It is suitable for AC current measurement and monitoring, AC motor overload protection, electronic switch of automatic control system, etc.
