Enhanced Poly-Phase, High-Performance, Wide-Span Energy Metering IC

Mais documentos...

The ATM90E32AS is an enhanced high-performance energy metering device for three-phase four-wire (3P4W, Y0) or three-phase three-wire (3P3W, Y or Δ) systems. With the measurement function, it can also be used in power monitoring instruments which need to measure voltage, current, mean power, etc. Compared to the ATM90E36A, it contains many enhanced functions such as piecewise non-linear compensation, enhanced anti-tampering monitoring and expanded event-detecting function.

Principais recursos

  • Fully compliant with IEC62052-11, IEC62053-22 and IEC62053-23, ANSI C12.1 and ANSI C12.20
  • Applicable in class 0.5S or class 1 poly-phase watt-hour meter or class 2 poly-phase var-hour meter
  • Accuracy of ±0.1% for active energy and ±0.2% for reactive energy over a dynamic range of 6000:1
  • Temperature coefficient is 6 ppm/°C (typical) for on-chip reference voltage; Automatically temperature compensated
  • ±1°C (typical) temperature sensor accuracy
  • Flexible piecewise non-linear compensation: three current- (RMS value) based segments with two programmable thresholds for each phase. Independent gain and phase angle compensation for each segment.
  • Electrical parameters measurement: less than ±0.5% fiducial error for Vrms, Irms, mean active/reactive/apparent power, frequency, power factor and phase angle
  • 6 dedicated ADCs and different gains for phase A/B/C current and voltage sampling circuits
  • Current sampled over Current Transformer (CT) or Rogowski coil (di/dt coil)
  • Programmable power modes
  • Fundamental (0.2%) and harmonic (1%) active energy with dedicated energy/power registers and independent energy outputs
  • Enhanced event detection: sag, over voltage, phase loss, over current, reverse V/I phase sequence, reverse flow, calculated neutral line current INC over-current and frequency upper and lower threshold
