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

URB1D05YMD-6WHR3A2S is chassis mounting of with heat sink, URB1D05YMD-6WR3A4S 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.
