(see figure 1). if you want to further decrease the input/output rippl e, you can increase capacitance properly or choose capacitors with low esr. however, the capacitance should not be too high , or may cause start-up problem . for every channel of output, provided the safe and reliable operation is ensured, the greatest capac itance of its filter capacitor sees (table 1).if you want to use the products in high emi, please choose our metal packaged products (pwa_md-1w 5 & pwb_md- 1w5). general: cin: 24v&48v 10 f~47 f cout: 10 f/100ma 3) input current when it is used in unregulated power supply, be sure that the fluctuating range of the power supply and the rippled voltage do not exceed the module standard. input current of power supply should afford the startup current of this kind of dc/dc module.
