These products apply to:
* 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
1) Where the voltage of the input power supply
is wide range (voltage range≤ 4:1);
2) Where isolation is necessary between input
and output(isolation≤1500VDC);
listed.
ISOLATION SPECIFICATIONS
3) Where the regulation of the output voltage
and the output ripple noise are demanded.
