Mean Well's LP Constant Voltage LED Drivers run off line voltage (90-264). We offer the LP series in 20, 35, 60 and 100 Watt models that act as a switching device to turn AC input voltage into a single-output DC voltage between 5 and 48V. These AC/DC power supplies come in a fully isolated plastic case that is IP67 rated so you can use outdoors without worrying about moisture getting inside. The slim, butterstick design allows you to work this into your lighting design easily and seamlessly. The wire connections are UL rated and run from 14-18 AWG depending on the Wattage you select (see data sheets below for specifics). If you have specifications and standards for your project, you should know this is a class 2 power unit. This low cost, high reliability unit is just what you need for large LED arrays needing a constant voltage supply.
