Regulated 12V 0.5A AC-DC Power Adapter, 5.5x2.1mm Barrel Jack

This regulated switch-mode power adapter converts standard mains power into a stable 12V DC supply at up to 0.5A. Fitted with a standard 5.5x2.1mm centre-positive barrel plug and a 2-pin EU plug, it is ideal for powering microcontrollers, dev boards, and low-power electronics projects. It provides a reliable power source for makers, hobbyists, and classroom STEM setups.

Stable DC power output

The adapter delivers a regulated 12V DC output with a maximum current of 0.5A and a minimum load current of 0mA. It features tight line regulation of +/- 1%, load regulation of +/- 5%, and a ripple and noise rating of 150mV peak-to-peak.

Wide universal input

Designed to handle global mains voltages, the unit accepts an input range of 90Vac to 270Vac (100Vac to 240Vac rated) at 47Hz to 63Hz. It features an integrated 2-pin EU plug and low standby power consumption of 0.1W maximum at no load.

Standard connection and reach

Power is delivered through a 1.2m cord terminating in a common 5.5x2.1mm centre-positive DC barrel jack, making it directly compatible with standard DC sockets on various electronics.
