After releasing the constant voltage LED power supplies from 18W to 100W, Mean Well Enterprise Co. Ltd. has extended the wattage to 150W, unveiling LPV-150 series, a constant-voltage LED switching power supply with plastic enclosure. This series accepts 180- to 305-Vac inputs and provides a choice of 12-V, 15-V, 2-4V, 36-V and 48-V outputs, the five most-frequently-used dc voltages for LED applications. LPV-150 is a class II (no FG) power unit, equipped with the 94V-0 flame retardant plastic case. In addition, it does not have the active PFC function, which allows LPV-150 to be highly-competitive in terms of cost.
LPV-150 series adopts the IP67 protection level design, preventing the internal electrical components from the damage of dust and moisture. The interior of this model is fully-potted with heat-conducting silicone, effectively enhancing the heat dissipation capability; moreover, with an efficiency of up to 90%, the entire series can work under -25 to +65 degrees C with free air convection. The input and output ends are paired with 18AWGx2C and 14AWGx2C wires, respectively, that facilitate the assembly at various types of system or operating environments.
Other functions cover the short circuit protection, the overload protection, the over voltage protection and the over temperature protection. The targeted applications include the indoor and outdoor LED signage, LED decorative lighting, building wall wash lighting, LED strips, and so on, in luminaires using constant-voltage LED driving.
