Product Details

BA series AC current sensor

General

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.Application 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.

Example of Wiring

As shown in the figure,the input is lac.The output of current output sensor is the current source with common GND while the output of voltage output sensor is the voltage source with common GND.In this example,RL is the user load.If the output is current,the load is up to 400Ω(with 12V power supply) or 800Ω(with 24V power supply). If the output is voltage,the load is 1kΩ or above.
