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
URB1D05LMD-10WHR3A2S is chassis mounting of with heat sink, URB1D05LMD-10WR3A4S 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, 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 a further decrease of the input and output ripple is required, properly increase the input & output of additional capacitors Cin and Cout
or select capacitors of low equivalent impedance，and ensure the capacitance should be lower than the max. capacitive load of the
product.
