Product Overview
Description
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 get more accurate and more timely control, but can also greatly simplify the design and reduce costs.
Features:
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 no limit 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.
8. The outer casing is made of self-extinguishing material ABS.
9. Suitable for AC current measurement and monitoring, AC motor overload protection, electronic switch of automatic control system
and so on.
