APPLICATIONS
The PWA_(M)D-3W & PWB_(M)D-3W Series
are specially designed for applications where a
wide range input voltage power supplies are

isolated from the input power supply in
a
200
20
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≤ 4:1);
2) Where isolation is necessary between input
and output (isolation≤1500VDC);
* 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.
3) Where the regulation of the output voltage
and the output ripple noise are demanded.
