Note: ①URB1D_LMD- 15W(H)R3 series CE certification standards for EN62368- 1 and EN50155; RB1D_LMD-20W(H)R3 series CE certification standards for EN60950- 1 and EN50155; ②Use“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; ③Absolute maximum stress rating without damage (not recommended); 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. | |||||||
