Notes：
① product model with a suffix of “A2S” means chassis mounting and that with a suffix of “A4S” indicates DIN-Rail mounting (e.g. URF2405LP-20WR3A2S means
chassis mounting; URF2405LP-20WR3A4S means DIN-Rail mounting );
②Absolute maximum rating without damage on the converter, but it isn't recommended;
③Efficiency is measured In nominal input voltage and rated output load;A2S (wiring) and A4S (rail) Model due to input reverse polarity protection, minimum
efficiency greater than Min.-2 is qualified.

Design Reference
1. Typical application
All the DC/DC converters of this series are tested according to the recommended circuit (see Fig. 2) before delivery.
If it is required to further reduce input and output ripple, properly increase the input & output of additional capacitors Cin and Cout or
select capacitors of low equivalent impedance provided that the capacitance is no larger than the max. capacitive load of the product.
