Recommended Circuit All the WRE_YD-5W&WRE_YD-5W Series have been tested according to the following recommended testing circuit before leaving factory.This series should be tested under load(See figure 1). If you want to further decrease the input/output ripple,you can increase capacitance properly or choose capacitors with low ESR. However, the capacitance of the output filter capacitor must be proper. If the capacitance is too big, a startup problem might arise. For every channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees (Table 1). General: Cin: 5V＆12V 100μF 24V＆48V 100μF-47μF Cout: 10μF/100mA RECOMMENDED CIRCUIT Output Graph Input current While using unstable power source,please ensure the output voltage and ripple voltage do not exceed indexes of the converter. Input current of power supply should afford the startup current of this kind of DC/DC module (See figure 2).
