Setting Up The Evaluation Board As An Energy Meter - Analog Devices EVAL-ADE7903EBZ User Manual

UG-797
SETTING UP THE EVALUATION BOARD AS AN
ENERGY METER
Figure 8 shows a typical setup for the
evaluation board. In this example, an energy meter for a 1-phase,
2-wire distribution system is shown. A shunt is used to sense
the phase current and is connected as depicted in Figure 8. The
line voltage is connected directly to the board, and the board is
supplied from one power supply provided by the PC through
the USB cable.
The ADE7903 can be used in conjunction with the
ADE7913/ADE7912 in a single-phase system to monitor both
the line and the neutral, if needed. In an alternative application
where isolation from the neutral line is not required, the
ADE7903 can be used on the neutral in a 3-phase distribution
system, along with three ADE7913/ADE7912
isolated ADC allows isolation from the line, while the
can be used on the neutral where isolation may not be required.
To evaluate the ADE7913, refer to the

Using the Evaluation Board with Another Microcontroller
It is possible to manage the EVAL-ADE7903EBZ
board with a different microcontroller mounted on another
board. The evaluation board can be connected to this second
board through the P8 connector, shown in Figure 9. In this case,
the SDP-B Blackfin board is unused.
