1. Mutual inductance current monitoring has high current detection accuracy and safe isolation of input and output. 2. Self-powered, no external power supply required. 3. Easy to install and use, no need to connect DC into the circuit when measuring. 4. Measured current AC 0-10/20/50A, output signal DC 0-10V. 5. Straight-through structure design, isolation withstand voltage up to 2000V. 6. Hysteresis is less than 1% and can be used under strong magnetic conditions. 7. The outer casing is made of self-extinguishing material ABS. 8. Suitable for AC current measurement and monitoring, AC motor overload protection, electronic switch of automatic control system and so on.
