No parallel connection or plug and play. Use dual output simultaneously,forbid pening output pin (0V) to use as single output. Note: 1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically. 2. Operation under 10% load will not damage 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 data sheet, all the test methods of indications are based on corporate standards. 5.
