The B_S-1W & B_D-1W Series are 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);
Note: The B_S-W2 & B_D-W2 series also are available in our company.
3) Where the regulation of the output voltage and
the output ripple and noise are not demanding.
Such as: purely digital circuits, ordinary low
frequency analog circuits and IGBT power device
driven circuits, etc.
