MAXQ3180 Maxim, MAXQ3180 Datasheet - Page 96

• 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 signed register contains the real instantaneous power delivered into phase A/B/C or total at the fundamental line
frequency only. Power is calculated from the instantaneous energy measurement according to the following equation:
