Two Power Modes Detect Meter Tampering
The ADE9078 AFEs offer two power modes to detect meter tampering. The PSM2 power mode uses a low-power comparator to compare current channels to a threshold. The PSM2 power mode then indicates whether the threshold is exceeded on the IRQ0 and IRQ1 outputs. The PSM1 power mode enables fast measurement of current and voltage RMS (xVRMS and xIRMS), active power, and VAR during a tampering incident.
