The Mean Well ELG-240-C2100DA is a single-output enclosed type AC/DC LED power supply that provides up to 240 W of output power. It offers models in 12V, 24V, 36V, and 48V output voltages. Its high efficiency and low no-load power consumption make it an ideal choice for LED lighting applications. It has adjustable output voltage from 10-20% of the rated voltage and can be combined with external PFC power supplies to provide a total power solution. The ELG-240-C2100DA also features both constant voltage (CV) and constant current (CC) operation and has built-in active PFC, over-voltage, current-limit, and short-circuit protection. It features a built-in fan with temperature controlled speed, allowing for silent operation during low-load conditions. This power supply is UL, CUL, TUV, and CE certified.
