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
URF1D05LD-40WHR3A2S is chassis mounting of with heat sink, URF1D05LD-40WR3A4S 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;
②The 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;
③Absolute maximum rating without damage on the converter, but it isn't recommended;
④Efficiency 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. 3) 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.
