Digital 3-Phase 3-Wire AC Voltage Transducer  NB-AV3C1-□□MB

  AV3C1 series is a Digital 3-phase 3-wire AC Voltage transducer.It detects the voltage in a wire, processes it, and then generates RS232/RS485 signal that could be used to recover the measured voltage. Processing by using the advanced MCU and precisive 24-digit AD Converter, this transducer has the advantage of high precision and superior performance.
