Notes: ①Part No. with suffix of “A2S” means chassis mounting and suffix of “A4S” means DIN-Rail mounting (e.g. URB2405YMD-10WR3A2S means chassis mounting;
URB2405YMD-10WR3A4S 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. ④The capacitive loads of positive and negative outputs are identical.

Note: ① When the input voltage from 18V down to 0V, the under-voltage protection to work; When the input voltage rises from 0V to 7-8V range, the output voltage decreases
with increasing load, but does not affect customers ② the voltage of Ctrl pin is relative to input pin GND.
