*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 WRA_D-10W & WRB_D-10W 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.
