Details
Meanwell PLN-45-48 is 45W Single Output LED Power Supply with 48V36-48V0.95A0-0.95A45.6W4.6Vp-p43.6-51.8V. The model stands out with dustproof/waterproof plastic insulated enclosure with power factor correction. It complies with UL1310 class 2 low power energy regulations and has an output power supply less than 100VA or 5A under any conditions, greatly reducing the risk of electric shock technicians may encounter. The high dust and water resistance design protects the electronic components inside meeting the application requirements of high humidity environments. What’s more, PLN-45-48 adopts single-stage PFC architecture in the circuit design to achieve high PF value in the most economical way and fit Class C from the harmonic current requirements of the EU EN61000-3-2. The highest efficiency can reach 87.5%, so it can only use natural air cooling and heat dissipation to operate at -30℃~+50°C. The built-in standard functions include 277VAC input voltage capability, short circuit protection, overload protection, over voltage protection and over temperature protection, etc., and the input and output mode is equipped with 18AWG power cord, which is convenient for users to flexibly assemble in various systems or working situations. PLN-45-48 has also passed TUV/UL/CUL/CE and other international certifications, including UL1310, UL879 SAM list, EN61347-1, EN61347-2-13 and other lighting related regulations
