D-Link 48V 0.5A switching adapter

The D-Link DSA-0421S-50 is a 24W switching power adapter built for devices that require a 48V 0.5A supply. It suits networking hardware, VoIP phones or similar equipment that uses a 3.5x1.0mm barrel connector. The unit accepts a universal 100-240VAC input, making it usable worldwide with the correct mains cord.

24W output with 48V rail

Rated at 48V and 0.5A, the adapter delivers up to 24W continuous power. It comfortably runs compatible D-Link switches or access points within that envelope. Loads that exceed 0.5A or require a different voltage will not operate correctly, so the unit is not for higher-wattage gear.

3.5x1.0mm barrel with IEC cord

The output cable terminates in a 3.5x1.0mm centre-positive barrel plug that fits the specified D-Link models. A detachable IEC power cord is included for the AC inlet, though overseas purchases may ship without it. The adapter is supplied new in bulk packaging and may show minor cosmetic marks from handling.
