ADE7854A/ADE7858A/ADE7868A/ADE7878A FEATURES
Highly accurate; supports EN 50470-1, EN 50470-3,
IEC 62053-21, IEC 62053-22, and IEC 62053-23 standards
Compatible with 3-phase, 3-or 4-wire (delta or wye) meters,
and other 3-phase services
Supplies total (fundamental and harmonic) active, reactive,
and apparent energy and fundamental active/reactive
energy on each phase and on the overall system
0.1% error (typical) in active and reactive energy over a
dynamic range of 1000 to 1 at TA = 25°C
0.2% error (typical) in active and reactive energy over a
dynamic range of 3000 to 1 at TA = 25°C
Averaged rms measurements available in low ripple rms
registers
Supports current transformer and di/dt current sensors
Dedicated ADC channel for neutral current input
Estimated neutral current measurement by calculating the
rms of the sum of the phase currents in all 3 phases
0.1% error (typical) in voltage and current rms over a
dynamic range of 1000 to 1 at TA = 25°C
Supplies sampled waveform data on all 3 phases and on …
