An EU centre-negative 12V/3A DC-adapter reference features a 1m 20AWG lead and literal 5521mm jack information. Actual black and white choices are both 36W. Retain the centre-negative polarity with the selected output and complete receiving-connector drawing.
Define centre-negative mating at the equipment inlet
Identify full connector dimensions and how the 5521mm reference maps to the chosen end. Separate dimensional alternatives include 5.5×2.5mm, 4.0×1.7mm and 3.5×1.35mm. Record polarity, contact fit and the actual 12V/3A equipment function with the approved DC-end arrangement. Keep the chosen black or white 36W version associated with that electrical and physical drawing.
Specify the mains and lead construction
Input information includes 240V and 100–240V AC, with 50/60Hz references. PVC material information and 2464/2468 20/22AWG cable choices accompany the primary 1m 20AWG request. Length references include 1/1.2/1.5/1.8/2m and customised requirements. Agree the actual material role, cable build, reach and EU mains connection for the selected adapter.
Review the stated protection and order conditions
Short-circuit protection is described with auto recovery. Overvoltage and overcurrent references each state 120% minimum, and the leakage reference is 0.25mA maximum at 240V AC input. Agree applicable operating and acceptance conditions, with relevant FCC/CE information and the stated 12-month warranty terms.
Provide the reviewed centre-negative output, full connector and cable drawing with receiving-equipment requirements and quantity. Keep those details with the chosen 36W adapter for assessment against its actual inlet, connection reach and operating load.
