    1W Isolated DC DC Converter Module For Data Switching And Relay Driven Circuits

    Description

    A0303S-1WR2 is designed for use in distributed power supply systems and especially suitable in applications such as pure digital circuits,low frequency analog circuits,relay-driven circuits and data switching circuits,where:

    1.The voltage of the input power supply is relatively stable with a variation of±10%Vin or less; 2.An input to output isolation voltage of up to 1500VDC is necessary;

    3.The requirement for a tight line and load regulation is not as strict.

    Such as pure digital circuits,low frequency analog circuits,relay-driven circuits and data switching circuits.
