ARCTIC

ARCTIC 12V 10A 120W AC/DC Adapter 5.5x2.1mm

SKU CH-GJ30-GF80J

Delivers 12 V DC at up to 10 A (120 W) from 100–240 V AC with a 5.5 × 2.1 mm barrel jack and screw-terminal adapter for LED strips, routers, cameras and other 12 V devices

  • Universal 100-240V input powers equipment worldwide
  • 12V 10A output delivers up to 120W for demanding loads
  • 5×2.1mm barrel jack fits common DC devices
  • Screw-terminal female connector enables wiring without soldering
  • Over-current protection safeguards connected electronics from damage

12 V 10 A 120 W power adapter

This ARCTIC adapter converts 100–240 V AC mains power into a regulated 12 V DC output capable of supplying up to 10 A. It is intended for hobbyists, technicians and installers who need a reliable 120 W source for 12 V equipment such as LED strips, CCTV cameras, routers or 3D printers. The unit is not a battery charger and must not be used with laptops or other battery-powered devices.

5.5 × 2.1 mm barrel jack with screw terminal

A 5.5 mm outer-diameter barrel plug with a 2.1–2.5 mm inner pin fits the included female DC connector, which accepts bare wires secured by screw terminals so no soldering is required. The adapter operates on 50 or 60 Hz supplies worldwide and includes over-current protection that shuts down the output if the load exceeds 10 A, protecting connected hardware from damage.

Replaces lower-wattage 12 V bricks

Builders currently using a 12 V supply rated below 120 W can upgrade to this model when their project demands more current, for example when driving longer WS2811, WS2815, 5050 or 5630 LED runs. It is unsuitable for any device that requires a charging profile or a voltage other than 12 V, and it cannot deliver more than 10 A continuous output.

Questions about this item

How much continuous current can the 12 V 120 W adapter deliver before its over-current protection trips?

The adapter supplies up to 10 A continuously; the built-in over-current protection activates if the load exceeds 10 A.

Does the power supply run silently or does it have a fan that adds noise during all-day operation?

The unit has no fan and operates silently, producing only the faint hum typical of a sealed switching supply.

What connector does my LED strip or device need to mate with the 5.5 × 2.1 mm barrel jack on this adapter?

Your device must accept a 5.5 mm outer-diameter, 2.1–2.5 mm inner-diameter DC barrel plug, the standard size on the included cable.
