ADI's self-calibrating energy metering IC simplifies embedded energy metering

Analog Devices, Inc. (ADI) today announced an energy metering IC that automatically calibrates in single-phase energy metering applications. The new ADE9153A features mSure® technology that automatically calibrates the metering system, significantly reducing the time, labor, and equipment costs required for calibration. The ADE9153A is the only energy metering IC on the market with auto-calibration capabilities that enables designers of intelligent lighting, data centers, electric vehicle charging, and industrial applications to easily integrate billing-level accurate energy metering into their products. Conventional energy metering ICs require expensive external reference and current sources for calibration, while the ADE9153A uses mSure technology to calibrate the system based on direct measurements of the metering system's energy metering signal path. If the ADE9153A is used in the engineering of the product, it can be automatically calibrated during production without the need to build, maintain and deploy a precision calibration rack on the production floor.

The ADE9153A supports active energy standards, including IEC 62053-21, IEC 62053-22, EN50470-3, OIML R46, and ANSI C12.20. It also supports reactive energy standards IEC 62053-23 and IEC 62053-24. The ADE9153A features power quality measurements such as zero-crossing, line-cycle calculations, angle measurements, dips and swells, peak and overcurrent detection, and power factor measurements.

ADE9153A Product Highlights:

Fast automatic calibration based on direct measurement of the metering signal path

No external reference current and voltage source required

Supports 0.5 and 1 level energy metering accuracy

3 high performance ADCs with SNR of 88 dB and a high gain current channel

Advanced metrology features: Watt, VAR, VA, Zx, sudden drop, jerk, peak, overcurrent, etc.
