APPLICATIONS
The B_XD-1W Series is specially designed
for applications where a single power supply
is isolated from the input power supply in a
distributed power supply system on a circuit
board.

These products apply to:
1) Where the voltage of the input power
supply is fixed (voltage variation ≤±10%);
2) Where isolation is necessary between
input and output (isolation voltage
=1000VDC);
3) Where the regulation of the output voltage
and the output ripple noise are not
demanded.
Such as: purely digital circuits, ordinary low
frequency analog circuits.
These products don’t apply to:

otherwise our company’s FS(D)-1W Series
of products are recommended;
3)Circuits in which the output voltage
regulation is demanded, otherwise our
company’s IB Series or WRB Series are
recommended.
