APPLICATIONS
The WRE_P-3W & WRF_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.
These products apply to:

1) Where the voltage of the input power supply is
wide range (voltage range≤2:1);
200
20
*Input voltage can’t exceed this value, or will cause the permanent damage.
2) Where isolation is necessary between input
and output(Isolation Voltage≤3000VDC);
3) Where the regulation of the output voltage and
the output ripple noise are demanded.
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.
