PWB4815CS-2W 15 133 13 80 These products apply to: 1) Where the voltage of the input power supply is wide range (voltage range≤ 4:1); * Input voltage over it may cause permanent damage to the device. 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. 2) Where isolation is necessary between input and output(isolation≤1500VDC); 3) Where the regulation of the output voltage and the output ripple noise are demanded.
