Product OverviewCZCL 40A/200W Ultra-Thin LED Display Power Supply (LDK-200-X Series) is an AC/DC switching power supply purpose-built for driving LED display panels, cabinets, and video walls. It converts 180-264VAC mains input into a stable 5Vdc output at up to 40A (200W), using a narrow AC input design in an ultra-thin housing that relies on natural convection cooling with an auxiliary heat sink, avoiding the need for a fan. The unit complies with IEC/EN/UL 62368-1 and GB4943.1 safety standards for high reliability and stability.
