Description
- Product Details
- The ADE9078 is a highly accurate, fully integrated energy metering device. Interfacing with both current transformer (CT) and Rogowski coil sensors, the ADE9078 enables users to develop a 3-phase metrology platform, which achieves high performance for Class 1 up to Class 0.2 meters.
- The ADE9078 integrates seven high performances ADCs and a flexible DSP core. An integrated high end reference ensures low drift over temperature with a combined drift of less than ±25 ppm/°C maximum per channel, each of which includes a programmable gain amplifier (PGA) and ADC.
- The ADE9078 offers an integrated flexible waveform buffer that stores samples at a fixed data rate or a sampling rate that varies based on line frequency to ensure 64 points per line cycle. These two options make it easy to implement harmonic analysis in an external processor according to IEC 61000-4-7.
- Two power modes are provided to enable detection of meter tampering: PSM2 uses a low power comparator to compare current channels to a threshold and indicates whether it is exceeded on the IRQ0 and IRQ1 outputs; PSM1 enables fast measurement of current and voltage rms (xVRMS and xIRMS), active power, and VAR during a tamper.
- The ADE9078 allows advanced and highly accurate energy measurements, enabling one platform to cover a wide range of meters, through a combination of various high end metrology features and superior analog performance.
