APPLICATIONS

The A_S-2W & B_S-2W Series are designed for application

where isolated output is required from a distributed power

system.

These products apply to where:

1)

Input voltage variation

≤ ±10%;

2)

1KVDC input and output isolation;

3)

Regulated and low ripple noise is not required.

Such as: digital circuits, low frequency analog circuits, and

IGBT power device driving circuits.
