产品概述
ATM90E32AS-AU-R is an enhanced poly-phase high-performance wide-span energy metering IC. It incorporates 6 independent 2nd order sigma-delta ADCs, which could be employed in three voltage channels (phase A, B and C) and three current channels (phase A, B, C) in a typical three-phase four-wire system. The M90E32AS has an embedded DSP which executes calculation of active energy, reactive energy, apparent energy, fundamental and harmonic active energy over ADC signal and on-chip reference voltage. The DSP also calculates measurement parameters such as voltage and current RMS value as well as mean active/reactive/apparent power. A four-wire SPI interface is provided between the M90E32AS and the external microcontroller. Application includes poly-phase energy meters of class 0.2S, 0.5S and class 1 which are used in three-phase four-wire (3P4W, Y0) or three-phase three-wire (3P3W, Y or Δ) systems, power monitoring instruments which need to measure voltage, current, mean power, etc.
- Accuracy of ±0.1% for active energy and ±0.2% for reactive energy over a dynamic range of 6000:1
- Temperature coefficient is 6ppm/°C (typ.) for on-chip reference voltage
- Automatically temperature compensated
- ±1°C (typ.) temperature sensor accuracy
- Active and reactive (forward/reverse), apparent energy with independent energy registers
- Programmable start-up and no-load power thresholds
- Programmable power modes normal, idle, detection and partial measurement mode
- Current and voltage instantaneous signal monitoring
- Programmable voltage sag detection and zero-crossing output
- TQFP48 package, industrial temperature range from -40°C to +85°C
