*Input voltage can

’t exceed this value, or will cause the permanent damage.

Note: The load shouldn't be less than 10%, otherwise ripple will increase dramatically.

Operation under 10% load will not damage the converter; However, they may not meet all specification

listed.

APPLICATIONS

The WRB_ZP-3W &WRA_ZP-3W 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

≤ 2:1);

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.
