PRELIMINARY TECHNICAL DATA
Recommendation
The sensitivity to ground noise of the analog section of the
system leads to select with cautious the set up of the
evaluation board.
To obtain the best performances from the evaluation board,
when it is used in a real meter configuration (Voltage = 220V
and current sensor connected), the configuration of Table1
should be applied.
This set up requires three 5volts Power supplies, an addi-
tional Ferrite Bead (Type Panasonic, EXCELSA391) and
the disconnection of U2.
If the CF pin is used to measure the accuracy of the system,
the connection between the ADE7756's CF pin and the input
of the opto-isolator should be restored by connecting U2.8
and U2.9 -
Figure 13
. The trace between BNC2 connector and
the SUB-D25 P1 connector should also been cut if this
connector is used to connect a PC via the parallel cable
