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.
