ATM90E32AS Demo Board

Part Number: ATM90E32AS-DB

Summary:

ATM90E32AS Poly-Phase Energy Metering Demo is used for the demo and testing of ATM90E32AS (poly-phase energy metering AFE chip), which can sample poly-phase voltage and current, meter active/reactive/apparent/fundamental/harmonic energy and output these energy pulses accordingly, as well as measure parameters such as voltage, current and power.

The AFE Control Board - SAM4C communicates
