1Part No. with suffix of “A2S” means chassis mounting and suffix of “A4S” means DIN-Rail mounting (e.g. URB2405YMD-6WR3A2S means chassis mounting;
URB2405YMD-6WR3A4S means DIN-Rail mounting);
2The minimum input voltage and starting voltage of A2S (wiring) and A4S (rail) Model are 1VDC higher than those of DIP package due to input reverse
polarity protection function.
3Absolute maximum rating without damage on the converter, but it isn't recommended;
4Efficiency 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;
5The capacitive loads of positive and negative outputs are identical.
