Atmel M90E26
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 which need to measure voltage, current, etc. The ADC and DSP technology ensure the chip's longterm stability over variations in grid and ambient environmental conditions.| Part No. | M90E26 |

FEATURES
MeteringFEATURES
● 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.● 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 over a dynamic range of 5000:1 for active energy; no cali- bration needed for reactive energy.
● Energy Meter Constant doubling at low current to save verification time.
● Electrical parameters measurement: less than ±0.5% fiducial error for Vrms, Irms, mean active/ reactive/ apparent power, frequency, power factor and phase angle.
● Forward/ reverse active/ reactive energy with independent energy registers. Active/ reactive energy can be output by pulse or read through energy registers to adapt to different applications.
● Programmable startup and no-load power threshold.
