ENERGY MEASUREMENT FEATURES
Proprietary analog-to-digital converters (ADCs) and digital
signal processing (DSP) provide high accuracy active
(WATT), reactive (VAR), and apparent energy (VA)
measurement
Less than 0.1% error on active energy over a dynamic
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 (ADE5569 and ADE5169 only)
Less than 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, IEC 62053-23,
EN 50470-3 Class A, Class B, and Class C, and ANSI C12-16
