We recommend to choose modules with a heat sink for enhanced heat dissipation and applications with extreme temperature requirements; 2 The A2S and A4S Model's start-up and minimum input voltages are increased by 1VDC due to the input reverse polarity protection circuit; 3 Absolute maximum stress rating without damage (not recommended); 4 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. 2019.03.19-A/3 Page 1 of 9 MORNSUN Guangzhou Science & Technology Co., Ltd. reserves the copyright and right of final interpretation DC/DC Converter URB_YMD-20WR3 Series Input Specifications Item Operating Conditions Min.
