It should also be noted that the capacitance of filter capacitor must be proper. If the capacitance is too big, a startup problem might arise. For every channel of output, provided the safe and reliable operation is ensured, the recommended capacitance of its filter capacitor sees (Table ).

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. 3. Max. Capacitive Load tested at nominal input voltage and constant resistive load. 4. All specifications measured at Ta=5 C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 5. In this datasheet, all the test methods of indications are based on our corporate standards. 6. All characteristics are for listed model, non-standard models may perform differently, please contact our technical person for more detail. 7. Contact us for your specific requirement. 8.
