Notes: ①Use “A2S” suffix for chassis mounting and “A4S” suffix for Din-Rail mounting; ②The A2S and A4S Model’s start-up and minimum input voltages are increased by 1VDC due to the input reverse polarity protection circuit; ③Exceeding the maximum input voltage may cause permanent damage; ④Efficiency 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; ⑤The specified maximum capacitive load value for Vo1 and Vo2 output is identical.
