Tomantery Normally Closed Adjustable SZC03-NC-AL-CH Current Sensing Switch 0.5-200A Scientific for Automation Industrial Equipment
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 signal 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 reaction speed reaches the ms level. 6.Straight-through structure design, isolation withstand voltage up to 2000V. 7.Hysteresis is less than 1 Percent and can be used under strong magnetic conditions. 8.The outer casing is made of self-extinguishing material ABS. 9.Widely used 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: 0.3A135V AC/DC Input straight-through current: 0.5-200A AC Switch on minimum: 0.5±0.2A Maximum overload of straight-through current: 200 Percent Accuracy: 10 Percent Power consumption: =1W Leakage current
