APPLICATION

The PWB_ZP-3WR2 Series are specially designed for

applications where a wide range input voltage power

supplies are unregulated from the input power supply in a

distributed power supply system on a circuit board.

These products apply to where:

1)

Input voltage range

≤4:1;

2)

1.5KVDC input and output isolation;

3)

Output regulated and low ripple noise is required.
