Key Document
Description
The TIDA-00601 design implements a Class 0.5% three-phase energy measurement system with isolated shunt sensors. The isolation is achieved through the use of isolated delta-sigma modulators that have output circuitry capacitively isolated from input circuitry. An energy measurement SoC takes the different bit-streams from the isolated modulators and uses its on-board digital filters to produce ADC sample readings. The energy measurement SoC is also used for sensing voltages, calculating metrology parameter values, driving the board’s LCD, and communication to a PC GUI via the board’s isolated RS-232 circuitry.
This reference design uses the ISO7420 and ISO7421. This reference design can also be used with the ISO7320C and ISO7321C.
This reference design uses the AMC1304M05. This reference design can also be used with the AMC1304M25.
This reference design uses the MSP430F67641. This reference design can also be used with the MSP430F67641A.
Features
- Class 0.5% three-phase metrology with galvanically isolated shunt current sensors
- Shunt isolation with working isolation voltage up to 1 kV AC and peak isolation voltage of 7kV
- TI Energy Library firmware calculates all energy measurement parameters including active and reactive power and energy, RMS current and voltage, power factor, and line frequency
- Isolated RS-232 with 3 kV RMS operating isolation boundary for communication to PC GUI
- Built-in 160-segment display for display of metrology parameters
