DEWIN Current Sensing Switch, Normally Open Switch Adjustable AC 0.2 30A SZC23 NO AL CH for Substation Frequency Conversion Speed Control Devices and Other Automation Industries

【High-quality Material】: The shell is made of self-extinguishing material ABS. Compared with traditional transformers, thermal protectors and other devices, using this current switches can not only obtain more accurate and timely control, but also greatly simplify the design and reduce costs. 【High Performance】: Self-powered, without external power supply, AC current sensing switch uses the principle of mutual inductance to sense AC direct current, isolate AC current, output normally open or normally closed switch signals, and directly control various automated industrial equipment. 【Professional Design】: Straight-through structure design, isolation voltage up to 2000V. The AC current detection switch is designed and manufactured to solve the AC current monitoring. 【Quick Response】: High-power MOS tube non-contact electronic switch, and the switch has no limit on the number of opening and closing times, and the response speed reaches the ms level. 【Application】: Action current 0.2-30A AC, adjustable potentiometer. Applicable to AC current measurement and monitoring, AC motor overload protection, automatic control system electronic switch, etc.
