1、The shell is made of self‑extinguishing ABS material, self‑powered, no external power supply is needed, and the AC current 0.5/5A‑200AAC can be adjusted by a potentiometer. 2、LED status indicator, can conveniently and intuitively indicate the working status of the switch, high‑power MOS tube non‑contact electronic switch. 3、The switch has no limit on the number of on‑off times, the response speed reaches the ms level, the through‑core structure design, and the isolation withstand voltage is up to 2000V. 4、The hysteresis is less than 1%, and it can be used under strong magnetic field conditions. The maximum AC and DC load of the switch is 0.3A 135V AC/DC. 5、It has the advantages of high accuracy, stable performance and long service life. It is an ideal choice for automatic industrial control equipment and power monitoring. 1 x Current Mutual Inductance Switch Item Type: Current Mutual Inductance SwitchMaterial: PlasticModel: SZC03-NO-F-CHSwitch Type: Normally OnCurrent Jump Value: Not AdjustablePower Supply: Self-PoweredInput Through-Core Current: 0.5-200A ACRated Load: 0.3A at 135V AC/DC (Can not be exceeded in any case)Minimum Value of Switch Conduction: 0.5± 0.2AThe Maximum Overload of the Through-Core Current: 200%, the through-core current cannot exceed 200% of the rated valueAccuracy: 10%Power Consumption: ≤1WMaximum Leakage Current: ≤1mAHysteresis: ≤1%Response Time: ≤200msWorking Temperature: -30~70℃Humidity: 0-95% (No Condensation)Square Bore Diameter: Approx. 20 x 20mm/ 0.8 x 0.8inApplication: Widely used in substations, frequency conversion speed regulation devices, inverter devices, electrolytic plating, electric locomotives, street lamp monitoring, coal mines and other automation industries that require current monitoring.Product Introduction:SZC03 series AC current induction switch is designed and produced to solve AC current monitoring. It uses the principle of mutual inductance to isolate AC current by inducing AC through-core current, output a normally open or normally closed switching signal, and directly control various automated industrial control equipment Compared with traditional transformer, thermal protector and other devices, using this device can not only obtain more accurate and timely control effects, but also greatly simplify design.
