V_SS
Negative Supply voltage.
IVN1, IVN2, IVN3 ^{The current into the A/D converter should be set at 14µARMS at nominal mains}
voltage. The voltage sense input saturates at an input current of ±25µA peak.
Inputs from current sensors. The shunt resistor voltage from each channel is
IIN1, IIP1, IIN2, IIP2,
IIN3, IIP3
converted to a current of 16µA_RMS at rated conditions. The current sense input
saturates at an input current of ±25µA peak.
VREF
This pin provides the connection for the reference current setting resistor.
A 24kW resistor connected to V_SS sets the optimum operating condition.
TCLK, TEST
Test inputs. For normal operation these pins must be connected to V_SS.
FOUT
Pulse rate output. The pulse frequency is proportional to the sum of the power
measured on all three phases. The pulse format also indicates the direction of
energy flow.
DIR
Direction output. This output indicates the direction of energy flow.
PGM0, PGM1
FOUT Pulse format Select. These inputs define the FOUT pulse width
and format.
