MAXQ3180 Maxim, MAXQ3180 Datasheet - Page 50

• 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

Low-Power, Multifunction, Polyphase AFE
This register contains the value by which the raw accumulated energy value in each phase is multiplied before being
presented to the virtual energy registers. The table below lists the raw energy accumulators and the corresponding
virtual registers.
* These registers represent the algebraic sum of the positive and reverse energy in the two “raw” registers noted. Thus, the energy
returned in these virtual registers represents the net energy.
