ENERGY MEASUREMENT FEATURES
Proprietary analog-to-digital converters (ADCs) and digital
signal processing (DSP) provide high accuracy active
(watt), reactive (var), and apparent energy (volt-ampere
(VA)) measurement
<0.1% error on active energy over a dynamic range of
1000 to 1 @ 25°C
<0.5% error on reactive energy over a dynamic range of
1000 to 1 @ 25°C (ADE7169 and ADE7569 only)
<0.5% error on root mean square (rms) measurements
over a dynamic range of 500 to 1 for current (Irms) and
100 to 1 for voltage (Vrms) @ 25°C
Supports IEC 62053-21, IEC 62053-22, and IEC 62053-23;
EN 50470-3 Class A, Class B, and Class C; and ANSI C12-16
Differential input with programmable gain amplifiers (PGAs)
supports shunts, current transformers, and di/dt current
sensors (ADE7169 and ADE7569 only)
