1W isolated DC-DC converter Fixed input voltage, unregulated single output
Description
A_XD-1WR3&B_XD-1WR3 series are specially designed for applications where an(two)isolated voltage is required in a distributed power supply system.They are suitable for:
1.Where the voltage of the input power supply is stable(voltage variation:±10% Vin); 2.Where isolation is necessary between input and output(isolation voltage≤1500VDC); 3.Where do not has high requirement of the ripple&noise of the output;
4.Typical application:pre-interference isolation,ground interference elimination,pure digital circuit,voltage isolation conversion,general low frequency analog circuit,relay drive circuit,etc.
