APPLICATIONS
9
The WRD_S-1W 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.

*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.

By connecting a low ESR capacitor between
this terminal and the pin-7(Figure 1), the output
ripple and noise may be further improved.
Generally, the capacitance is no greater than
47uF.

To ensure this module can operate efficiently
and reliably, During operation, the minimum
output load is not less than 10% of the full load,
If the actual load is less than the specified
minimum load, the output ripple may increase
sharply. 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.

Recommended Circuit
If you want to further decrease the
input/output ripple, you can increase
capacitance properly or choose capacitors with

However, the capacitance of the output filter
capacitor must be proper. If the capacitance is
too big, a startup problem might arise. For
every channel of output, provided the safe and
