Three Phase AC Voltage and Current Transducer with Isolated DC Analog Outputs Reference Design
Description
The TIDA-00454 TI design demonstrates using the MSP430F67791A device to accurately measure voltages and currents.
This design also demonstrates using two DC analog output channels, which are capable of being individually configured for voltage output (±10 V) or current output (±24 mA).
The design has six digital outputs that can be used to drive relays. The functionality of the design can be extended to measure power.
The advantages of this design is that it is a complete system for measuring voltages and currents and providing a DC analog output proportional to the AC inputs.
Another advantage of this design is the bidirectional DC analog output.
