Note: ①Use“F/H”suffix for heat sink 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 tested at nominal voltage 48V and full load at +25C ambient. | |||||||
