FUNCTIONAL DESCRIPTION

1.

Power Calculation

In the Application Circuit (see Figure 2), the output current from the current sensor

will be between 0 and 16µA (0 to 80A through a shunt resistor of 625

µΩ). The current

input stage saturates at input currents greater than18µA

The mains voltage

(230V + 15% -20%) is used to supply the circuitry with power and for the power

calculation, together with the current information from the current sensor (shunt

resistor).

The SA9106AP integrated circuit may be adjusted to accomodate any voltage or

current values. The method of calculating external component values is described

in paragraph 5 (Circuit Description).

SAMES offers two evaluation module options, namely 230V/80A and 115/80A.
