Typical connection of AC current transducer

din rail energy meter

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.

BA series residual current sensors are designed to monitor the electric leakage and detect the insulation of electrical circuit or electrical equipment in order to avoid accidents arising from reduction of insulation performance of electrical circuit or electrical equipment.The product complies with GB/T13850-1998 and GB1208-2006.
