Notes:
1
Use “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;

The A2S and A4S Model’s start-up and minimum input voltages are increased by 1VDC due to the input reverse polarity protection circuit;
Absolute maximum stress rating without damage (not recommended);
Efficiency 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.
