Current Sensors for High-precision Measurement TRJC20-12A

This product utilizes the basic magnetic principle combined with multi-channel feedback compensation technology to operate the sensor in a zero magnetic flux state, with extremely high measurement accuracy. Due to the insensitivity of the magnetic flux of the sensor core to temperature, the sensor made using the zero magnetic flux principle not only measures AC and DC simultaneously, but also has the characteristics of being less affected by environmental temperature, high measurement accuracy, wide measurement frequency band, and good stability.
