APPLICATIONS

The B_S-1W & B_D-1W 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.
