URF2405LP-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.

Design Reference
1. Typical application
All the DC/DC converters of this series are tested according to the recommended circuit (see Fig. 2) before delivery.
If it is required to further reduce input and output ripple, properly increase the input & output of additional capacitors Cin and Cout or
select capacitors of low equivalent impedance provided that the capacitance is no larger than the max. capacitive load of the product.

1. Packing Information please refer to 'Product Packing Information'. Packing bag number : 58210039(DIP),58220022(A2S/A4S package);
2. Recommended used in more than 5% load, if the load is lower than 5%, then the ripple index of the product may exceed the
specification, but does not affect the reliability of the product.
3. The max. capacitive load should be tested within the input voltage range and under full load conditions;
4. Unless otherwise specified, data in this datasheet should be tested under the conditions of Ta=25℃, humidity<75% when inputting
nominal voltage and outputting rated load;
5. All index testing methods in this datasheet are based on our Company’s corporate standards;
6. The performance indexes of the product models listed in this datasheet are as above, but some indexes of non-standard model
products will exceed the above-mentioned requirements, and please directly contact our technicians for specific information;
