ATM90E26-YU-R is a single-phase high-performance wide-span energy metering IC. The ADC and DSP technology ensure the chip’s long-term stability over variations in grid and ambient environmental conditions. The M90E26 is used for active and reactive energy metering for single-phase two-wire (1P2W), single-phase three-wire (1P3W), or anti-tampering energy meters. With the measurement function, the M90E26 can also be used in power instruments that need to measure voltage, current, etc. Metering features fully in compliance with the requirements of IEC62052-11, IEC62053-21, and IEC62053-23; applicable in class 1 or class 2 single-phase watthour meter or class 2 single-phase var-hour meter.
Features:
- Accuracy of 0.1% for active energy and 0.2% for reactive energy over a dynamic range of 5000:1
- Temperature coefficient is 15ppm/ °C (typical) for on-chip reference voltage
- Energy meter constant doubling at low current to save verification time
