Note:
①series
with suffix "A2S" are chassis mounting, with suffix "A4S" are DIN-Rail mounting, for example URB1D05XD-10WA2S is chassis mounting , URB1D05XD-10WA4S
is DIN-Rail mounting;
②Absolute
maximum rating without damage on the converter, but it isn't recommended;
③The
efficiency of "A2S" and "A4S" is approx. 2% lower for the protection of inverse polarity.

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.
