Notes:
1
Part No. with suffix of “A2S” means chassis mounting and suffix of “A4S” means DIN-Rail mounting (e.g. URA2405YMD-10WR3A2S means chassis mounting;
URA2405YMD-10WR3A4S means DIN-Rail mounting);
2
The 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;
3
4
Absolute maximum rating without damage on the converter, but it isn't recommended;
Efficiency 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;
5
The capacitive loads of positive and negative outputs are identica.
