MAXQ3180 Maxim, MAXQ3180 Datasheet - Page 93

• Manufacturer Part Number: MAXQ3180
• Description: The MAXQ3180 is a dedicated electricity measurement front-end that collects and calculates polyphase voltage, current, power, energy, and many other metering and power-quality parameters of a polyphase load
• Manufacturer: Maxim

This signed register provides the raw apparent energy accumulated over the most recent DSP cycle.
This signed register accumulates energy in the same fashion as the X.ACT register, but only at the fundamental line
frequency.
