APPLICATIONS

The A_(X)T-W2 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.
