The input current of the power supply must be sufficient - All of the VWRBS2-SIP Series have been tested to the startup current (Ip) of the DC/DC module according to the following recommended testing (Figure 2) circuit before leaving the factory. This series should be tested under load(Figure 1). If you want to further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with Ip low ESR. However, the capacitance should not be too high(Table 2).
