  • This product is a combined current transformer that can simultaneously detect lightning current and AC high current. The two-way current inputs and outputs are completely isolated, with high isolation voltage. The product is safe and reliable, and the signal is electromagnetically isolated, which makes the output signal and the input signal have a linear relationship. The product has the advantages of high precision, fast response and simple installation. It can be widely used in real-time detection/monitoring of lightning current and AC high current signals, computer field data acquisition, industrial control, PLC measurement and control and other automatic control systems.
