DESCRIPTION
The Teridian™ It supports both Delta and Wye configurations. At the measurement interface, the device provides six analog inputs including three differential current and three voltage for interfacing to current and voltage sensors. The device provides better than 0.5% accuracy over a wide 2000:1 dynamic range. The integrated MPU core and 128 KB of flash memory provide a flexible means of configuration, postprocessing, data formatting, interfacing to host processor via a UART or SPI interface, or using DIO pins for LEDs or relay control. Complete firmware is available from Maxim and can be loaded into the IC during manufacturing test. Functional Diagrams 19-6039; Rev 2; 4/12 78M6631 3-Phase PowerMeasurement IC DATA SHEETFEATURES
