Overview

The AS044 energy meter power supply is a 10W isolated multi-channel AC/DC flyback converter that has a special requirement to pass magnetic tampering using an iron dust core. The design is made to operate at 450V AC, and it has a capacitor saver function which will help in reducing the BOM and increasing the reliability.

AS044 Energy Meter Power Supply Board
AS044 Energy Meter Power Supply Board
  • Flyback AC/DC supply to withstand 450V AC with avalanche rated 900V, 13ohm integrated MOSFET
  • Iron dust core to pass 0.5T magnetic tampering as per IEC standard
  • Capacitor Saver feature to save on BOM cost and improve reliability
  • Isolated dual channel outputs which have 4KV isolation between primary and all secondary outputs
  • Configurable overload timer of the device allows 100msec peak demand of 2A
  • Pulse frequency Modulation (PFM) for light load implementation, pulse width modulation (PWM) changes from 50KHz to 3KHz
