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.

... PM2005FPD CIRCUIT DESCRIPTION ANALOG SECTION The analog (metering) interface described in this section is designed for measuring 3x 230V/60A than Class 1. The most important external components for the SA2005F integrated circuit are the current sense resistors, the voltage sense resistors and the bias setting resistor. The resistors used in the metering section should be of the same type so that temperature effects are minimized ...

... PM2005FPD POWER SUPPLY Referring to figure 10, capacitor C10 is charged through D2 during the positive half of the sine wave from the R29, C12 mains voltage dropper. Identical charging circuitry exists for the other two phases. During the negative sine wave, C11 is charged through diode D1. The unregulated voltage charged on C10 and C11 is limited means of zener diode D7 ...
