APPLICATIONS

The PWA_LT-1W5 & PWB_LT-1W5 series are

specially designed for applications where a wide

range input voltage 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

wide range(voltage range

≤4:1);

2) Where isolation is necessary between input

and output (isolation voltage

≤1500VDC);

3）Where the regulation of the output voltage and

the output ripple noise are demanded.
