DescriptionLPH-18 Series are 18W AC/DC enclosed, non PFC design, switching power supplies. LPH-18 models offer constant voltage mode and high IP rating to protect the electronic components from dust and moisture, making suitable for use in harsh locations. LPH-18 Series possesses high efficiency and can operate between -30°C ~ +70°C using only free air convection. To protect the unit from sudden high surge for unstable AC line, LPH-18 can withstand 300VAC input surge for 5 seconds.
