Product Description
The IBM PA-1121-07I AC Adapter is a powerful and specialized power supply unit designed to provide a substantial 16V DC output at a high current of 7.5A, totaling 120 watts of power. This makes it suitable for demanding applications and devices that require more power than typical consumer electronics. The adapter converts standard AC mains voltage into the required DC power, ensuring stable and reliable operation for the connected equipment. A key distinguishing feature of the PA-1121-07I is its 4-pin connector. This type of connector is often used in industrial or enterprise environments where a more secure and robust connection is necessary compared to standard barrel connectors. The 4-pin configuration can provide multiple power and ground connections, or potentially include a signaling pin, ensuring a firm connection that is less prone to accidental disconnection, which is critical for uninterrupted operation of sensitive or high-power systems. While the title specifies 'AC Adapter', it's important to note that this unit's primary function is to convert AC input to a specific DC output. The 16V/7.5A specification suggests compatibility with certain IBM servers, workstations, docking stations, or other specialized equipment that requires this particular power profile. Users must verify that their device's power input requirements precisely match the PA-1121-07I's output specifications, including the 4-pin connector type, before use.
