The voltage to this pin should be mid-way between V and V . DD SS Positive Supply voltage. Negative Supply voltage. The current into the A/D converter should be set at 14µA at nominal mains RMS 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 converted to a current of 16µA at rated conditions. The current sense input RMS saturates at an input current of ±25µA peak. This pin provides the connection for the reference current setting resistor. A 24kW resistor connected to V sets the optimum operating condition. SS Test inputs. For normal operation these pins must be connected to V . SS 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. Direction output. This output indicates the direction of energy flow. FOUT Pulse format Select. These inputs define the FOUT pulse width and format.
