Features Self-powered, no external power required. Suitable for AC current measurement and monitoring, AC motor overload protection, automatic control system electronic switch, etc. Mutual inductor current monitoring has high current detection accuracy and safe isolation of input and output. Measured current AC 0-100/150/200A, output signal DC 0-10V. The outer shell is made of self-extinguishing ABS material. Hysteresis is less than 1% and can be used under strong magnetic conditions. Direct structure design, isolation withstand voltage up to 2000V.
