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 625µΩ). The current
input stage saturates at input currents greater than18µA
RMS
. 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.
The calculated power is directly displayed on a 5 digit (7 segment) LED display. The
update interval is approximately every 2 seconds.
