WAWEIS 12V AC Adapter for Buffalo LinkStation 420 220

SKU CH-S5DZ-BHDEH

12 V AC adapter replaces Buffalo LinkStation 420 and 220 NAS power supplies with 10 ft cord and FCC, CE, RoHS certification

  • World-wide 100-240 V input works anywhere
  • 10 ft total cord length reaches distant outlets
  • Over-current, over-voltage and short-circuit protection built in
  • FCC, CE and RoHS certified for safety
  • 100 % compatible with LinkStation 420 and 220 models

Compatible NAS Models

This 12 V AC adapter replaces the original power supply for Buffalo LinkStation 420 and 220 series units, including LS420D0202, LS420D0402, LS420D0802 and LS220D0202. It matches the Sunfone ACD048A2-12 and Tech STD-1240P specifications for direct compatibility.

Upgrade Considerations

The adapter serves as a direct replacement when the original supply fails or is lost; it is not an upgrade that adds capacity or speed. Buyers needing redundant power for multi-bay enclosures or higher wattage for expanded drives should verify their NAS requirements before purchasing.

Installation Notes

Connection is straightforward: plug the IEC mains lead into a 100-240 VAC outlet and the barrel connector into the NAS power port. The 10 ft total cord length aids placement. Ensure the jack polarity and voltage match the device label to avoid damage; no driver or firmware steps are required.

Questions about this item

What barrel-plug size does the WAWEIS 12V adapter use for the LinkStation 420?

The adapter ships with the original centre-positive barrel connector that matches the LinkStation 420 LS420D0202, LS420D0402 and LS420D0802 power sockets.

How do I connect the 10 ft cord to the NAS without stressing the jack?

Route the cable so the ferrite bead sits near the unit, then plug the barrel straight in — forcing it sideways is the step most people get wrong.

When should I replace the adapter if the NAS runs 24/7?

Plan on a new unit after roughly 12 months of continuous operation; the built-in over-current, over-voltage and short-circuit protections degrade with sustained load.
