Genuine Netgear 48V power adapter

This genuine DVE adapter supplies 48 volts at 0.8 amps for compatible Netgear networking equipment. It accepts a universal 100 to 240 VAC input at 50 to 60 Hz with a 1.2 amp draw. A standard IEC power cord is included in the package.

Replaces lost or faulty 38 watt supplies

The unit delivers up to 38 watts of regulated output, matching the original specification for supported devices. Swapping to this adapter is worthwhile when the existing supply shows voltage drift, connector damage or complete failure. It restores reliable operation without modifying the host equipment.

Limited to barrel connector 5.5 by 2.1 mm

The fixed output plug uses a 5.5 mm outer diameter and 2.1 mm centre pin, so it only fits jacks with that exact geometry. Polarity and voltage are not adjustable, preventing use with hardware that requires a different connector size or pinout. Buyers needing a different tip or voltage must select another model.

Questions about this item

What barrel connector size does the DSA-0421S-50 use for the device side?

The adapter terminates in a 5.5 x 2.1 mm barrel connector that plugs into the powered device.

How do I connect the included power cord to the adapter?

Plug the supplied IEC power cord into the adapter’s inlet, then insert the barrel plug into the device; the step often missed is seating the barrel plug fully until it clicks.

When should the DSA-0421S-50 be replaced?

Replace the unit if the output voltage drifts from 48 V, the barrel connector becomes loose, the cord shows fraying, or the adapter overheats during normal use.
