*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_YMD-6W/WRB_YMD-6W 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 dem anded.
