1) Recommended circuit
The P20H series is been tested according to the following recommended test circuit before leaving the factory (see Figures 1).
If you want to further decrease the input / output ripple, you can increase a capacitance values properly or choose capacitors with
low ESR, but the total capacitance of the filter capacitor must not exceed the maximum load capacitance value (see „Model guide“
table).

Note:
1. Min. load should not 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. The recommended unbalanced load of dual output converter should be low than 5 %. If the load asymmetry greater than 5 %,
it may not be guaranteed to meet all specifications listed. Please contact our technical support for more details.
3. Maximum 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. Specifications of this product are subject to changes without prior notice.
9. It is not recommended to increase the output power capability by connecting two or more converters in parallel. The converters
are not hot swappable
