DescriptionLPC-20 Series are 20W AC/DC enclosed, non PFC design, switching power supplies. LPC-20 models offer constant current mode and high IP rating to protect the electronic components from dust and moisture, making suitable for use in harsh locations. LPC-20 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, LPC-20 can withstand 300VAC input surge for 5 seconds.
