AC DC Desktop, Wall Adapters are electronic power supply units (PSU) that convert alternating current (AC) power, the type of power supplied to homes and businesses, to direct current (DC), the type of power used by most consumer electronics. This type of power supply is essentially a voltage reducing transformer that converts high voltage AC line power to a lower voltage that is more suitable for electronic components. L6R250DM-480-C14 is one such power adapter.

The L6R250DM-480-C14 desktop adapter is a 250W, wall mountable electronic power supply. It is capable of delivering 14A of continuous output current while providing a regulated, low ripple, DC voltage output of 48Vdc. It is compliant with the latest safety requirements including UL/cUL qualifications and CCC approval. This power adapter is also RoHS compliant and meets Class I Energy efficiency regulations. The unit is universal input, making it suitable for use in a wide variety of countries, and has a small form factor making it suitable for use in limited space conditions.

The power adapter features short circuit protection, over current protection, over voltage protection, and thermal protection, to ensure the safety of the power supply and the connected device. The external AC/DC power supply also features built-in fan cooling to ensure stable operation and improved thermal performance.

A practical application of this power adapter would be in LED lighting systems, where up to fifty high-power LED bulbs can be driven in series, requiring a high current output with minimal flickering. As the L6R250DM-480-C14 is capable of delivering a particulary low rippple with a high current output, it is the ideal power adapter for this purpose.

The working principle of the L6R250DM-480-C14 power adapter is simple. It essentially consists of an AC/DC power supply unit, a rectified, smoothed DC voltage output, and a regulated DC voltage output. The AC/DC power supply converts the low voltage AC line power into high voltage DC power, by rectifying and smoothing the AC input with a full-bridge rectifier and an LC filter. This high voltage DC power is then regulated in order to generate a constant voltage output, with low ripple, by a built-in voltage regulator.

In summary, the L6R250DM-480-C14 power adapter is a wall mountable power supply that can deliver 14A of continuous output current. It is suitable for use in LED lighting systems, or other applications requiring a regulated low ripple DC voltage output. This power adapter has built-in over current, over voltage, short circuit and thermal protection to keep the power supply and connected device safe. The working principle of the power adapter consists of an AC/DC power supply, full-bridge rectifier and LC filter, and a voltage regulator.
