Notes：

1

Part 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);

2

Absolute maximum rating without damage on the converter, but it isn't recommended;

3

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.

4

The capacitive loads of positive and negative outputs are identical.
