nodehawknodehawk AC Current Sensing Switch Current Sensing Relay 0-200A Normally Closed Current Sensor Monitoring Relay,Linkage PLC Signal,Overload Controller (M3086)
Main highlights- Upgrade: Compared with traditional transformers, thermal protectors and other devices, using this device can not only get more accurate and timely control, but also greatly simplify the design and reduce costs. Self-powered, no external power supply required. Input through current: 0-200A AC Rated load: 0.3A@240V AC/DC
- Multi-Purpose: M3086 AC current sensing switch is specially designed and manufactured to solve AC current monitoring. It uses the principle of mutual inductance to sense AC direct current, isolate the AC current, output normally open or normally closed switch signals, and directly control various automated industrial equipment, such as flash lamps, buzzers, relays, microcontrollers or other power load equipment
- LED Indication: The action current is 0-200A AC, which can be adjusted by the potentiometer. The LED indicator light can easily and intuitively indicate the working status of the switch
- High Performance: The switch has no limit on the number of times of opening and closing, and the response speed reaches the millisecond level. The hysteresis is less than 1% and can be used under strong magnetic conditions. Through structure design, isolation withstand voltage up to 2000V
- ABS material: High-power MOS tube non-contact electronic switch is used, and the shell is made of self-extinguishing material ABS, which is heat-resistant, acid-alkali-resistant, high impact strength and stable in performance
