Self-calibrating energy metering IC simplifies embedded electricity measurement

Analog Devices has a new energy metering IC with autocalibration for single-phase energy measurement applications. The ADE9153A uses mSure technology to automatically calibrate the measurement system, significantly decreasing calibration time, labour and equipment costs. As the only energy measurement IC with autocalibration, the device allows designers of intelligent lighting, EV charging, datacenter, and industrial applications to add with ease billing-grade accurate energy measurement to their products. Traditional energy measurement ICs need calibration using expensive, external reference grade voltage and current sources. In contrast, the device uses mSure technology to calibrate the system based on direct measurements of the metering systems energy measurement signal path. Products engineered to use the device can auto-calibrate during production, bypassing the requirement to build, maintain and deploy precision calibration racks on the production floor. The device supports active energy standards including IEC 62053-21, IEC 62053-22, EN50470-3, OIML R46, and ANSI C12.20. Reactive energy standards IEC 62053-23 and IEC 62053-24 are also supported. The IC includes power quality measurements such as zero crossing detection, angle measurement, line period calculation, dip and swell, peak and overcurrent detection, and power factor measurements.
