Note: ①Use“F”suffix is for added aluminum baseplate and“H”suffix for heat sink mounting. Use ”A5”suffix for chassis mounting and“A6”suffix for DIN-Rail mounting. We recommend to choose modules with a heat sink for enhanced heat dissipation and applications with extreme temperature requirements; ②”P”means positive logic,“N”means negative logic; ③Exceeding the maximum input voltage may cause permanent damage; ④The minimum input voltage range and the start-up voltage of the A5/A6 product model are 1VDC higher than the horizontal package. |
