Introducing the SZC03 series AC current sensing switch. Made from self-extinguishing ABS material, this switch is self-powered, eliminating the need for an external power supply. The switch can adjust the AC current from 0.5/1.5A to 200AAC using a potentiometer.
It features an LED status indicator, allowing for convenient and intuitive indication of the switch's working status. The switch is equipped with a high-power MOS-tube-free electronic switch, ensuring reliable performance.
With no limitation on the number of on-off operations, this switch boasts an MS-level fast response time. Its continuous core structure allows for an isolation resistance voltage of up to 2000V. The hysteresis is less than 1%, making it suitable for use in strong magnetic field conditions. The maximum AC and DC load for the switch is 0.3A at 135V AC/DC.
This switch offers high accuracy, stable performance, and a long service life, making it an ideal choice for automatic industrial control equipment and power monitoring.
Item Type: Mutual Inductance Switch Material: Plastic Model: SZC03-NO-F-CH SWITCH TYPE: Normally On Current Jump Value: Not adjustable Power Supply: Self-powered Input Current Through Core: 0.5-200A AC Rated Load: 0.3A at 135V AC/DC (must not be exceeded under any circumstances) Minimum Value of Switch Conduct: 0.5 ± 0.2A The Maximum Overload of the Penetrating Core Current: 2100% (the penetrating core current must not exceed 2100% of the marking value) Accuracy: 10% Power Consumption: ≤1W Maximum Leakage Current: ≤1mA Hysteresis: ≤1% Response Time: ≤200ms Working Temperature: -30~70℃ Humidity: 0-95% (no condensation) Square Hole Diameter: Approx. 20 x 20mm/0.8 x 0.8in Usage: 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 power monitoring.
