ETSA-UD (18W) Series, AC DC Desktop, Wall Power Adapters

AC to DC desktop and wall adapters are compact and fully enclosed devices designed to convert electrical power from an alternating current (AC) input voltage to a direct current (DC) output voltage. These adapters are commonly used to power a wide range of electronic devices, such as laptops, smartphones, routers, and other consumer electronics. The main function of these adapters is to provide a safe and efficient conversion of electrical power. They take the AC voltage from a standard wall outlet, typically at 110-240 volts AC, and transform it into a different DC voltage suitable for the specific device being powered. The output voltage can vary depending on the requirements of the device, ranging from a few volts to several tens of volts. Desktop adapters are designed to be used on a flat surface, such as a desk or table, and typically have a cord that connects to the wall outlet. On the other hand, wall adapters, also known as wall-warts or plug-in power supplies, are directly plugged into the wall outlet without the need for a separate cord. They are usually compact in size and have a built-in prong or connector that fits directly into the outlet. These adapters are enclosed in a durable and heat-resistant casing to ensure safety and protection against electrical hazards. They often feature built-in safety mechanisms such as over-voltage protection, over-current protection, and short-circuit protection to safeguard both the adapter and the device being powered. AC to DC desktop and wall adapters play a crucial role in powering various electronic devices by providing a stable and regulated DC voltage. Their compact design, versatility, and safety features make them an essential component in our daily lives, enabling us to conveniently and safely power our electronic devices.
