APPLICATIONS

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.

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 & Vout1 and Vout2 (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.
