1ph AFE-V9265
The single-phase metering AFE V9265 features a built-in current sampling resistor achieving calibration-free user-level metering error. By achieving isolation between strong and weak electricity of power and communication inside the chip can integrate directly with the main control board system in order to avoid the problem of strong and weak electricity isolation caused by integrating metering function.
