Specification: SZC03 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 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 0.5-200A 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 speed reaches the ms . 6. Straight-through structure design, isolation withstand voltage up to 2000V. 7. Hysteresis is less than 1% and can be under strong conditions. 8. The outer casing is made of self-extinguishing material ABS. 9. Widely in automation industry that requires current monitoring such as substations, variable frequency speed control devices, inverter devices, electrolytic electroplating, street lamp monitoring, etc. Specification: Model: SZC03-NC-AL-CH Power supply: Not required Rated load: 0.3A@135V Input straight-through current: 0.5-200A AC Switch on minimum: 0.5±0.2A Maximum overload of straight-through current: 200% Accuracy: 10% Power consumption: Less than or equal to 1W Leakage current: Less than or equal to 1mA Hysteresis: Less than or equal to 1% Response time: Less than or equal to 200ms Working environment: -30~70 degrees Celsius , 0-95% : 62x90x25.5mm / 2.4x3.5x1.0in Hole diameter: 20mm / 0.8in Package weight: Approx. 84g/2.96oz Package list: 1 x Current Sensing Switch Note: 1. Due to the difference between monitors and light effects, the pictures may not reflect the actual color of the item. 2. Please allow slight error due to manual measurement. Thanks for your understanding.
