71M6515H
Description
The 71M6515H is a high-accuracy analog front-end (AFE) IC that provides measurements for 3-quadrant 3-phase metering. The bination of a 21-bit sigma-delta A/D converter with a six-input analog front-end, a thermally pensated high-precision reference, and a pute engine results in high accuracy and wide dynamic range.
Key Features
- < 0.1% Wh accuracy over 2000:1 range
- Exceeds IEC 62053/ANSIC 12.20 specifications
- Up to 10ppm/C precision ultra-stable voltage reference
- Single Converter Technology reduces cross talk and power consumption
- Six sensor inputs-referenced to V3P3
- compatible with CTs, resistive shunts and Rogowski Coil sensors
- Digital temperature pensation
- Sag detection
- Measures Wh, VARh, VAh, Vrms, Irms, V-to-V phase and load angle on each phase
- Four-quadrant metering
