Design Reference
1. Typical application
If it is required to further reduce input and output ripple, a filter capacitor can be connected to the input and output terminals, see Fig.3.
Moreover, choosing suitable filter capacitor is very important , start-up problems may be caused by too large capacitance. To ensured the
modules running well, the recommended capacitive load values as shown in Table 1.

Note: 1. 24V input series, is subject to CY (CY : 1nF/3KV).
2. It is not needed to add the component in the peripheral circuit when
parameter with the symbol of "--".
3. Output load requirements
To ensure themodulework efficiently and reliably, during theoperation, the min. output load should be no less than 10% of the full load. If the
actual output power is low, please connect a resister to the output terminal in parallel, with a recommenced resistance which is 10% of the
rated power, and derating is required during operation.
