Product Details
Product Overview
Hangte LPA-300-4.5 is a 270W fan-less LED display power supply from the LPA slim-case series with active power factor correction. It converts 90-264VAC mains input into a stable 4.5Vdc output at up to 60A, and is built for LED display panels, cabinets, video walls and LED indicator lighting. The ultra-thin 30mm housing suits a wide range of cabinet depths, while high efficiency, a compact shell and good heat dissipation keep it stable in long-duration operation. Every unit is 100% aging tested.
