Description

NJU9102/A is a digital detector IC for earth leakage current breaker. The built-in ADC converts from an analog signal from ZCT (Zero-phase-sequence Current Transformer) to digital data, and processes digital data based on an earth leakage current detector condition. As a result of data processing, NJU9102/A outputs a one-shot pulse on SCRT terminal when an analog signal is judged to a leakage condition, and turns on an external thyristor.

Applications

  • Earth Leakage Current Breaker
  • GFCI (Ground Fault Current Interrupter)
