MEAN WELL LED Driver, 27 → 54V Output, 25.2W Output, 1.05A Output, Constant Voltage Dimmable

LPF-25D series 25W dimmable LED driver power supply with a wide range universal AC input range of 90 to 305Vac, a built-in active PFC function and a "three-in-one" dimming function using a 1 to 10 Vdc or PWM signal or resistance. These LPF-16D series 16W dimmable LED driver power supplies have a class II AC input design (two wires without FG) and are fully potted by heat-conducted glue which provides an IP67 protection rating and an internal shock absorption to withstand 5G vibration. A high efficiency of up to 85% is also offered by these 25W dimmable LED driver power supplies and an ability to operate under a wide temperature range of -40 to +70° using free air convection. Typical applications for these 25W dimmable LED driver power supplies include LED lighting and moving sign applications in dry, damp or wet locations.
