APPLICATIONS
The WRE_CKS-1W & WRF_CKS-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(isolation voltage≤3000VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded.

* Designing. **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.
