Notes：①Series with suffix “H” are heat sink mounting; series with suffix “A2S” are chassis mounting，with suffix “A4S” are DIN-Rail mounting, for example
URB2405LD-20WHR3A2S is chassis mounting of with heat sink,URB2405LD-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;
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;
④ The capacitive loads of positive and negative outputs are identical.
