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.

DIR
Direction output. This output indicates the direction of energy flow.
FOUT Pulse format Select. These inputs define the FOUT pulse width
and format.
