TIDA-00454
概覽
This reference design uses the MSP430F67791A device to accurately measure voltage and current. It 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 advantages of this design is that it measures voltage and current and provides a DC-analog output proportional to the AC inputs. Another advantage is the bidirectional DC-analog output.
The design has six digital outputs that can be used to drive relays. The functionality of the design can be extended to measure power.
特點
- MSP430F67791A System-on-Chip (SOC) with six simultaneous delta-sigma ADCs for three current and voltage measurement
- Dual-output 16-bit DAC8563, XTR300 and ISO7341FC based. Programmable DC-voltage or current output; ±10-V DC or ±24 mA; unidirectional or bidirectional
- Digital outputs consist of six open collector outputs for driving relays, pulse and provided as open collector
- Voltage measurement range: 10% to 120% of rated voltage (230 V)
- Current measurement range: 5% to 200% of rated current (5 A)
- On-board current transformer and potential divider provided for direct measurement of voltage and current
