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

URE1D12LD-20WHR3A2S is chassis mounting of with heat sink, URE1D12LD-20WR3A4S 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;

②A2S (wiring) and A4S (rail) Model due to input reverse polarity protection function, input voltage range the minimum value and starting voltage is higher than

1VDC DIP package;

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.

⑤For the dual output modules, the capacitive loads of positive and negative outputs are the same.
