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. 4.
