Dell YCZX-1203000U 12V 36W Adapter
This Dell YCZX-1203000U is a 12V DC power adapter rated for 36W maximum output. It suits devices such as LED strip lights, CCTV security cameras, routers and small monitors that require a 12V supply up to 3A. The unit accepts a wide 100-240V AC input for worldwide use. It is not for devices that need more than 36W or a different output voltage.
Thermals Noise Power Draw
The adapter includes automatic overload, over-voltage, over-temperature and short-circuit cut-off protection. These safety features limit heat build-up and prevent damage during a fault condition. The external plastic jacket remains at a low temperature during normal operation. No fan is present, so the unit runs silently.
Barrel Connector Quick Wiring
A 5.5mm barrel connector with 2.1mm to 2.5mm inner diameter fits many common 12V devices. A supplied quick-wiring connector allows screw-terminal attachment without soldering. The 5-inch cable length keeps the adapter close to the device. The black plastic housing weighs 150 grams.

Questions about this item
How do I connect the 5.5 mm × 2.1 mm or 2.5 mm barrel plug and the included quick-wiring connector?
Match the device's 12 V DC input polarity, push the 5.5 mm barrel plug fully home, then use the screw-terminal quick connector for bare wires — no soldering needed.
What ongoing care does the 36 W adapter need?
Keep the ventilation slots clear of dust, inspect the 5.5 mm barrel and cable jacket for cracks, and replace the unit if the overload or over-temperature protection trips repeatedly.
What limits continuous operation of the 12 V 3 A supply?
The 36 W maximum output and built-in over-temperature cut-off; sustained loads near 3 A will trigger thermal shutdown before the adapter can overheat.
