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 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.
