Why choose 277VAC 24volt waterproof led power supplies?

The AC power supplied for commercial buildings and household in the USA and Canada are 110Vac or 120Vac. The input voltage of most LED power supplies is 100 - 240Vac, it is available. However, some commercial buildings need an input voltage of 277Vac, at this point, a wide voltage power supplies are needed, such as the Swin Power VT3.0 series, they are UL appr. UL file#: E507826, Class P, Type HL,...
