1) Recommended circuit The P20J series is been tested according to the following recommended test circuit before leaving the factory (see Figure 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). Figure 1 Figure 2, Recommended EMC circuit Input reflected ripple measure circuit The input reflected ripple current is measured with inductor Lin and capacitor Cin to simulate source impedance.

Note: 1. Minimum load should be more than 5 %, otherwise the ripple exceeds the specificated values. Operation at lower than 5 % load will not damage the converter. 2. Maximum capacitive load is tested within the input voltage range and at full load. 3. All specifications measured at Ta 25 °C, humidity < 75 %, nominal input voltage and rated output load unless otherwise specified. 4. It is not recommended to increase the output power capability by connecting two or more converters in parallel. 5. The converters are not hot swappable!
