APPLICATIONS
9
The WRD_S-1W 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.

*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.
