The WRD_(M) P-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.

1) Where the voltage of the input power supply is
wide range (voltage range ≤2:1);

2) Where isolation is necessary between
(Isolation Voltage ≤ 1000VDC);
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.
