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. 12 9.0-18 22 MODEL SELECTION WRE2412CKS-1W Rated Power Package Style Output Voltage Input Voltage Product Series W RF4809CKS-1W * W RF4812CKS-1W * W RF4815CKS-1W * * 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.
