Analog Devices ADE7761B Manuals

The ADE7761B is an energy measurement IC with on-chip fault and missing neutral detection. It supports the IEC 62053-21 standard and offers high accuracy and a large dynamic range. The IC provides active power on the frequency outputs for calibration. It continuously monitors phase and neutral current for fault detection in 2-wire distribution systems. It also continuously monitors voltage and current inputs for missing neutral detection. The IC is designed for current channel input using shunt or current transformer sensors, and uses the larger of the two currents (phase or neutral) for billing, even during a fault condition.

This is a high-precision, active energy measurement IC that supports IEC 62053-21 standard, with a dynamic range of 1000:1. This product has high precision, low power consumption, and no external power supply.
