1. Output Load Request a. To ensure this module operate efficiently and reliably, the minimum load recommended not to be less than 5% of the nominal load. If the actual power is too small, please connect a resistor in parallel at output terminal, the resistance equal to 5% nominal load. If use positive negative dual output product, please try to avoid big unbalances between loads, or the original output voltage accuracy cannot be ensured. b. The maximum capacitive load is tested under nominal input full load; if use it under no load condition, should try to decrease the output capacitive load...

4.Ripple& Noise Test*：(20MHZ bandwith) By Measurement Method： Ripple&Noise should be tested by the oscilloscope, in order to avoid the extra noise, the probe of the oscilloscope should directly connect to the output pin of the module, see the below photo: 5.Input Reflective Ripple Current Test Circuit: Capacitor C should choose low ESR type capacitor, the withstand voltage value should be larger the max input voltage value. Application Recommendation: 1.The recommended minimum load is 5%-10%, output ripple might rise under no load, other performances are not affected basically; 2. The recommended...
