Analog Devices ADE7761 Manuals

ADE7761 is a high accuracy active energy measurement IC, supports IEC 687/61036, with an error less than 0.1% over a dynamic range of 500 to 1. It supplies active power on the frequency outputs F1 and F2. The high frequency output CF is intended for calibration and supplies instantaneous active power. Continuous monitoring of the phase and neutral current allows fault detection in 2-wire distribution systems. Current channels input level best suited for current transformer sensors. Uses the larger of the two currents (phase or neutral) to bill—even during a fault condition. Continuous monitoring of the voltage and current inputs allows missing neutral detection. Uses one current input (phase or neutral) to bill when missing neutral is detected. Two logic outputs provide neutral missing and fault detection status.

ADE7761 is a high accuracy active energy measurement IC from Analog Devices, which supports IEC 687/61036 standard. Its dynamic range is 500:1 and the maximum measurement accuracy can reach 0.1%. It supports frequency outputs F1 and F2, and high frequency output CF for calibration and instantaneous active power supply. ADE7761 adopts continuous monitoring of phase current and neutral current to realize fault detection in 2-wire distribution systems. The current channel input level is suitable for current transformer sensors. In the case of a fault, the larger of the two currents (phase or neutral) is still used for billing. ADE7761 adopts continuous monitoring of voltage and current inputs to realize missing neutral detection. When missing neutral is detected, the current channel (phase or neutral) is used for billing. ADE7761 has two logic outputs that can be used for fault and missing neutral detection.
