FEATURES
INTRODUCTION
The PM4100AD evaluation module is designed to demonstrate
the functionality of the following devices SA4102A, SA2002E,
SA2002H, SA2002P, SA2002D and SA2102D. The module is
easily configured and setup for the various devices by means of
on-board jumpers. The setup of the module is simplified with the
help of the accompanying software that illustrates the jumper
positions for each device.
The measured energy is displayed on an on-board LED

... PM4100APD ANALOG INPUT The most important external components for any SAMES integrated circuit are the current and voltage sense resistors, as well as the bias setting resistors. These resistors must be of the same type as specified in the parts list to ensure that temperature effects and noise susceptibility is minimized. ...

... Resistors R2 and R3 (figure 3 and figure 4) define the current level into the current sense inputs of the device. The PM4100APD module can be configured to use any type of shunt or CT, but to ensure proper current sensing it is advisable to use a shunt or CT that will give a voltage drop of at least 20mV at maximum supply current. The resistor values are calculated for an input of 16µ ...
