Note:

1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically.

2. Operation under 10% load will not dam age the converter; However, they may not meet all specification listed.

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 corporate standards.

5. Only typical models listed, other models may be different, please contact our technical person for more details.
