OIAGLH 12V 4A 48W AC Adapter
This OIAGLH adapter delivers 12 volts at 4 amps for a total of 48 watts. It uses a 5.5 mm by 2.1 mm barrel connector compatible with SUN-1200400 and SOY-1200400 models. The unit suits monitors and similar devices that require this exact voltage and connector size. It is not for equipment needing a different voltage, current rating or plug diameter.
Thermals Noise and Power Draw
The adapter converts mains power to 12 V DC at up to 48 W during normal operation. It runs without a fan so audible noise is minimal in typical use. Heat output scales with the connected load and stays within the design limits of the sealed enclosure. No active cooling or external heatsink is required.

Questions about this item
How do I connect the 5.5 x 2.1 mm barrel plug to my monitor without reversing polarity?
Align the centre pin with the positive terminal and the outer sleeve with ground; the 12 V 4 A rating only delivers power when the tip polarity matches the monitor’s input marking.
When should I replace the 12 V 4 A adapter if the monitor starts flickering?
Replace it when output drops below 12 V under load or the 5.5 mm jack feels loose, as worn contacts or aged capacitors can no longer sustain the 48 W rating.
