URA2405LD-15WR2 Datasheet, PDF (2/9 Pages) MORNSUN Science& Technology Ltd. – DUAL/SINGLE OUTPUT DIP PACKAGING, DC-DC CONVERTER

Note: ①Series with suffix “H” are heat sink mounting; series with suffix “A2S” are chassis mounting，with suffix “A4S” are DIN-Rail mounting, for example URB2405LD-
15WHR2A2S is chassis mounting of with heat sink,URB2405LD-15WR2A4S is DIN-Rail mounting of without heat sink;If the application has a higher
requirement for heat dissipation, you can choose modules with heat sink;
②Absolute maximum rating without damage on the converter;
③For dual-output-converters the given value is for one output (for both outputs the same value);
④The efficiency of "A2S" and "A4S" is approx. 2% lower for the protection of inverse polarity.
