range of 1000 to 1 @ 25°C

Less than 0.5% error on reactive energy over a dynamic

range of 1000 to 1 @ 25°C (ADE7569 and ADE7169 only)

Less than 0.5% error on root mean square (rms)

measurements over a dynamic range of 500 to 1 for

current (I

rms

) and 100 to 1 for voltage (V

rms

) @ 25°C

Supports IEC 62053-21, IEC 62053-22, IEC 62053-23,
