Lite-On PA-1041-81 power adapter 12V 3.33A 40W

Replacement 40 W Monitor Adapter

The Lite-On PA-1041-81 is a 40 W AC adapter built to replace the original supply for monitors that require 12 V at 3.33 A. It accepts a universal 100-240 V input at 50-60 Hz and ships with a detachable power cord. The barrel connector measures 5.5 mm and matches the port on compatible displays. Buyers who need a higher wattage unit or a different output voltage should look elsewhere.

Continuous Load Behaviour

The adapter delivers its rated 40 W continuously across the full 100-240 V input range without relying on short-term peak ratings. Built-in protection guards against incorrect voltage, short circuit and internal overheating during extended operation. The unit is tested for broken wires, loose particles and jack integrity before shipping. No thermal throttle point or duty-cycle limit is specified in the data.

Decisive Specification: 5.5 mm Barrel Connector

The 5.5 mm centre-positive barrel plug is the single detail that determines whether this adapter fits the target monitor. Polarity, inner diameter and pin depth must match the device socket exactly or the supply will not connect. Verify the monitor's original part number or connector dimensions before ordering. Adapters with a different plug size cannot be used with this model.
