ES917 Board
ES917 board measures the mains voltage. It detects the three line voltages and it outputs three voltage
signals proportional to the inputs. These outputs may be proportional to phase to phase voltages (in that
case, they must not be used) or they may be proportional to each voltage phase to neutral (in that case, they
are allocated to the Energy Counter).
CAUTION
Exclusively use the ES917 board fitting the rated voltage of the grid it is to
be connected to (see below).
