Dell ALT-2403 24V 3A 72W Adapter
This Dell ALT-2403 power adapter converts 100V-240V AC input into a stable 24V DC output at up to 3A, delivering 72W maximum power. It features a 5.5mm x 2.1mm barrel connector and includes a UK three-pin AC plug, a 110cm DC cable and a free female DC connector for solderless wiring.
Suited for 24V LED strips.
The unit is built for constant-voltage loads such as 5050 or 3528 LED strip modules, wireless routers, switches and security camera systems that require exactly 24V DC. It is not suitable for devices needing a different voltage, higher current than 3A, or a connector size other than 5.5mm x 2.1mm.
Sustained-load protection
Automatic overload cut-off, over-voltage cut-off, thermal cut-off and short-circuit protection activate continuously during extended operation to guard connected equipment. The adapter is rated for ambient temperatures from -20°C to 50°C and up to 95% non-condensing humidity, ensuring reliable 72W delivery over long periods.
