Notes:①Use “H” suffix for heat sink mounting, “A2S” suffix for chassis mounting and “A4S” suffix for DIN-Rail mounting. We recommend to choose modules with a
heat sink for enhanced heat dissipation and applications with extreme temperature requirements;
②Exceeding the maximum input voltage may cause permanent damage;
③Efficiency is measured at nominal input voltage and rated output load; efficiencies for A2S and A4S Model’s is decreased by 2% due to the input
reverse polarity protection circuit;
