Maxim largesse ZON M3 single-phase energy meter SoC

maxim

Using the ZON M3 (MAX71315) single-phase electricity meter SoC from Maxim Integrated Products Inc., engineers now have a highly accurate, low-cost design system for e-meters and solid-state meters.

Superior metering metrology is essential for accurate monitoring and billing. Furthermore, meter manufacturers must consider cost in their designs, as millions of meters are being arrayed throughout the globe.

The ZON M3 energy-meter solution integrates four 24-bit ADCs for 4-channel data collection and ±0.1 percent measurement accuracy over 5000:1 dynamic range. A 32-bit metrology compute engine (CE) ensures high-accuracy processing of all collected data.

Its two touch-switch inputs eliminate mechanical switches and improve user experience, and its infrared (IR) communications interface eliminates the typical extra IR receiver module. All the high integration cuts cost and improves user experience.

Key advantages

Superior metering accuracy: over ±0.1% over 5000:1 dynamic range.

High integration: integrated touch-switch inputs and IR communications improve user experience and reduce system cost; multiple interfaces (SPI, I2C, and 4 USART) for design versatility; real-time clock (RTC) with temperature compensation and digital temperature sensor for highly accurate temperature compensation; ample Flash and RAM memory for long-term service.

High performance: a 32-bit metrology CE ensures high-accuracy processing of all collected data.

The ZON M3 electricity meter is available in a 100-pin LQFP package.
