The ATM90E26 is a high-performance energy metering device for single-phase two-wire, single-phase three-wire or anti-tampering active and reactive energy meters. With the measurement function, the ATM90E26 can also be used in power instruments which need to measure voltage, current, etc.

Additional Features:

Accuracy of 0.1% for active energy and 0.2% for reactive energy over a dynamic range of 5000:1.
Temperature coefficient is 15 ppm/ ℃ (typical) for on-chip reference voltage.
Single-point calibration for active energy, no calibration needed for reactive energy.
