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.
