Min. load shouldn‘t be less than 5%, otherwise ripple maybe increase dramatically. Operation under minimum load will not damage the converter, however, they may not meet all specification listed. 2. Max. Capacitive Load tested at nominal input voltage and constant resistive load. 3. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 4. In this datasheet, all the test methods of indications are based on our corporate standards. 5. All characteristics are for listed model, non-standard models may perform differently, please contact our technical person for more detail. 6. Contact us for your specific requirement. 7.

If it is required to further reduce input and output ripple, properly increase the input & output of additional capacitors Cin and Cout or select capacitors of low equivalent impedance provided that the capacitance is no larger than the max. capacitive load of the product. It is not allowed to connect modules output in parallel to enlarge the power.
