Part Details

  • High accuracy, active energy measurement IC supports IEC 62053-21
  • Less than 0.1% error over a dynamic range of 1000 to 1
  • Supplies active power on the frequency outputs, F1 and F2
  • High frequency output CF is intended for calibration and supplies instantaneous active power
  • Continuous monitoring of the phase and neutral current allows fault detection in 2-wire distribution systems
  • Current channel input level best suited for shunt and current transformer sensors
  • Uses the larger of the two currents (phase or neutral) to bill, even during a fault condition
  • Continuous monitoring of the voltage and current inputs allows missing neutral detection
  • Uses one current input (phase or neutral) to bill when missing neutral is detected
  • Two logic outputs (FAULT and REVP) can be used to indicate a potential miswiring, fault, or missing neutral condition
  • Direct drive for electromechanical counters and 2-phase stepper motors (F1 and F2)
  • Proprietary ADCs and DSP provide high accuracy over large variations in environmental conditions and time
