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.

2) Where isolation is necessary between
(Isolation Voltage ≤ 1000VDC);
3) Where the regulation of the output voltage and
the output ripple noise are demanded.
* 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.

If you want to further decrease the input/output
ripple, you can increase capacitance properly or
choose capacitors with low ESR. However, the
capacitance should not be too high, or may cause
start-up problem. If you want to use the products in
high EMI, please choose our metal packaged
products(WRD_MP-3W). For every channel of
output, provided the safe and reliable operation is
ensured, the greatest capacitance of its filter

APPLICATION NOTE
Requirement on output load
In order to ensure the product operate efficiently and reliably, in addition to a max load
(namely full load), a minimum load is specified for this kind of DC/DC converter. Make sure
the specified range of input voltage is not exceeded, the minimum output load no less than
10% load. If the actual load is less than the specified minimum load, the output ripple may
increase sharply while its efficiency and reliability will reduce greatly. If the actual output
power is very small, please add an appropriate resistor as extra loading, or contact our
company for other lower output power products.
