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.
