DESCRIPTION

The SA2005F IC is an enhancement of the SA9105F.

The PM2005FPD evaluation board provides energy data via

an isolated pulse output for three-phase four-wire applications

using the SA2005F. The mains voltages easily connect to the

module by way of a Molex connector (SK1). The 3 on-board

current transformers measure the current in each phase. A

simple capacitive power supply supplies the energy metering

IC with power. The LM431 regulators are used to generate 5V

supply voltage for the IC on the board.
