Еще документы...

The ATM90E36A is a high-performance energy metering device for three-phase four-wire (3P4W, Y0) or three-phase three-wire (3P3W, Y or Δ) systems. It is also applicable in Data Acquisition Terminal. With the measurement and Fourier analysis functions, the ATM90E36A can also be used in power monitoring instruments which need to measure voltage, current, THD, DFT, mean power, etc.

Ключевые особенности

  • Fully compliant with IEC62052-11, IEC62053-22 and IEC62053-23, ANSI C12.1 and ANSI C12.20
  • Applicable to 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
  • ±1°C (typical) temperature sensor accuracy
  • Electrical parameters measurement: less than ±0.5% fiducial error for Vrms, Irms, mean active/reactive/apparent power, frequency, power factor and phase angle
  • 7 dedicated ADCs and different gains for phase A/B/C current/voltage and Neutral line current sampling circuits
  • Current sampled over Current Transformer (CT) or Rogowski coil (di/dt coil)
  • Voltage sampled over resistor divider network or Potential Transformer (PT)
  • Programmable power modes: Normal mode, Idle mode, Detection mode and Partial Measurement mode
  • Fundamental (0.2%) and harmonic (1%) active energy with dedicated energy/power registers and independent energy outputs
  • Total Harmonic Distortion (THD) and Discrete Fourier Transform (DFT) functions for 2~32 order harmonic component analysis for each phase’s voltage and current.THD and DFT results available in SPI accessible registers
