APPLICATIONS
The
B_YS-W2
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)
2)
3)
Where the voltage of the input power supply
is fixed (voltage variation
≤ ±10%);
Where isolation is necessary between input
and output (isolation voltage≤1000VDC);
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.
