7 Note: 1. Min. load shouldn't be less than 5%, otherwise ripple maybe increased dramatically, If the product operates under min. load, it may not be guaranteed to meet all specifications listed. Operation under minimum load will not damage the converter. 2. Recommended Dual output models unbalanced load is ±5%, If the product operates >±5%, it may not be guaranteed to meet all specifications listed. Please contact our technical support for more details. 3. Max. Capacitive Load is tested at input voltage range and full load. 4. All specifications measured at Ta=25 C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 5. In this datasheet, all test methods are based on our corporate standards. 6. All characteristics are for listed models, and non-standard models may perform differently. Please contact our technical support for more details. 7. Please contact our technical support for any specific requirement. 8.
