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.

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.

*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.
