12 V 3 A power adapter
This Dell CY-123000 adapter converts AC mains voltage to a stable 12 V DC output rated at 3 A. It delivers up to 36 W through a 5.5 × 2.1 mm barrel plug with centre-positive polarity. The unit accepts 100 to 240 V input at 50 to 60 Hz and includes over-voltage, over-current and over-temperature protection. A 3.94 ft cable allows flexible placement for indoor devices.
Suitable for low-power 12 V equipment
This adapter suits CCTV cameras, DVRs, NVRs, routers, LED strips, audio boards and similar 12 V gear that draws no more than 3 A. It is not for devices requiring higher current, a different voltage, or a connector other than the 5.5 mm barrel type. Buyers needing more than 36 W or a USB-C power delivery profile should look at other products.
3 A maximum output current
The single specification that decides fit is the 3 A current limit at 12 V. Any load exceeding 3000 mA will trigger protection or risk damage, so the connected device must stay within this rating.

Questions about this item
How do I decide whether the 12 V 3 A model is right for my device?
Match the adapter only to equipment that requires exactly 12 V DC and draws no more than 3 A (36 W); exceeding that limit can cause failure or damage.
What does the 36 W rating actually deliver inside a live system?
It supplies a stable 12 V DC at up to 3 A from any 100–240 V AC outlet, with built-in over-voltage, over-current and over-temperature protection.
Which barrel-plug standard does the 5.5 mm × 2.1 mm connector follow, and what does that cap?
The tip-positive 5.5 mm × 2.1 mm plug also fits 5.5 mm × 2.5 mm jacks, limiting use to devices that accept centre-positive polarity and the stated voltage and current.
