Active Energy Metering Ic With Di/dt Sensor Interface - Analog Devices

The ADE7759 is an accurate active power and Energy Measurement IC with a serial Interface and a pulse output. The ADE7759 incor- porates two second order - ADCs a digital integrator (on CH1), reference circuitry, Temperature Sensor and all the signal processing required to perform active power and Energy Measurement An on-chip digital integrator allows direct Interface to di/dt Current Sensors such as a Rogowski coil. The digital integrator eliminates the need for an external Analog integrator and pro- vides excellent long-term stability and precise phase matching between the current and the voltage channels. The integrator CAN be switched off if the ADE7759 is used with conventional Current Sensors The ADE7759 contains a sampled Waveform Register and an Active Energy Register capable of holding at least 11.53 seconds of accumu- lated power at full ac load. Data is read from the ADE7759 via the serial Interface The ADE7759 also provides a pulse output (CF) with frequency that is proportional to the active power. In addition to active power information, the ADE7759 also provides various system calibration features, i.e., channel offset correction, phase calibration, and power offset correction. The part also incorporates a detection circuit for short duration voltage drop (SAG). The voltage threshold and the duration (in number of half-line cycles) of the drop are user programmable. An open drain Logic output (SAG) goes active low when a sag event occurs. By Analog Devices, Inc.
