Digital 3-Phase AC Current Transducer   NB-AI3C1-□□EB

AI3C1 series is a Digital single phase AC Current transducer.It detects the current in a wire, precesses it, and then generates RS232/RS485 signal that could be used to recover the measured current. Processing by using the advanced MCU and precisive 24-digit AD Converter, this transducer has the advantage of high precision and superior performance.
