PM2002DP

This application note describes the functionality of the SA2002D metering integrated circuit using the PM2002DP evaluation module.

The SA2002 enables the meter manufacturer to build a meter that measures the energy consumption, and records it to a mechanical counter. Energy flow direction as well as energy metering activity is indicated by means of LEDs. This application note will focus on the practical use of the SA2002D, more detailed information specific to the SA2002D can be found in the applicable datasheet.

The PM2002DP module connects directly to live and neutral on SCK1. The module is referenced to live and should be kept in mind when connecting test equipment to the module. The current is measured by the shunt on the top of the PCB. The left terminal of the shunt is connected to live. The live out will be connected to the right terminal of the shunt.
