Adjustable current detection switch, normally open, 0.2-30 A SZC23 NO AL CH

Overview

An AC current sensing switch designed for efficient current monitoring. It uses the principle of mutual inductance to detect AC/DC current, isolate it, and produce normally open or closed switching signals. This device is self-powered, meaning it does not require an external power supply, and offers high accuracy and a fast response. Technical Specifications Operating Current Range: 0.2-30 A AC Accuracy: 1% Offset: ≤ 1% Response Time: ≤ 200 ms LED Indicator: Yes Applications This switch is ideal for controlling automated industrial equipment, such as flashing lights, buzzers, relays, and microcontrollers. Its design allows for adjustments via a potentiometer to adapt to the different requirements of the equipment. It is widely used in substations, variable frequency drives, inverters, electrolytic plating, electric locomotives, street lighting monitoring, coal mines, and other industries requiring current monitoring.
