APPLICATIONS
The A_S-2W & B_S-2W Series are
specially designed for applications where a
group of polar power supplies are 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 demanding.
Such as: purely digital circuits, ordinary low
frequency analog circuits, and IGBT power
device driving circuits.
