Note: 1. 24V input series, 24V output series is subject to CY (CY : 1nF/2KV).
2. It is not needed to add the component in the peripheral circuit when

3. Output load requirements
When using, the minimum load of the module output should not be less than 10% of the nominal load. In order to meet the performance
parameters of this datasheet, please connect a 10% dummy load in parallel at the output end, the dummy load is generally a resistor,
Please note that the resistor needs to be used in derating.
