APPLICATIONS

APPLICATIONS

The QA-XS&QB-XLS 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.
