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 the module work efficiently and reliably, during the operation, 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.
