* 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.

APPLICATIONS

The WRD_(M) P-3W

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

(Isolation Voltage

≤ 1000VDC);

3) Where the regulation of the output voltage and

the output ripple noise are demanded.
