BA series conduct the real-time measurement on the alternating current in the power grid according to the electromagnetic induction theory. They utilize the precise constant current technology and the linear temperature compensation technology to isolate and convert the measured current into the DC signal.They adopt the 24V or 12V power supply. They feature the large overload capacity, high accuracy, isolation and safety and low power consumption. Applications cover the industrial automation sector.
