Description
This 5V 2.5A regulated AC to DC power supply provides stable power for your microcontroller projects and electronic circuits. Featuring a standard 2-pin EU mains plug and a centre-positive 5.5x2.1mm DC barrel connector, it delivers up to 2.5A of continuous current. It is ideal for students, hobbyists, and makers needing a reliable desktop power source.
Reliable regulated DC output
The adapter delivers a regulated +5V DC output with a maximum current of 2.5A and low ripple and noise of 150mV p-p. It offers +/- 1% line regulation and +/- 5% load regulation across current demands from 0mA up to full load.
Universal AC mains input
Equipped with a standard 2-pin EU plug, this unit operates across a wide rated AC voltage range of 100Vac to 240Vac (90Vac to 270Vac absolute range) at 47Hz to 63Hz. It features an efficient standby power load of at most 0.1W.
Convenient cable and connector
Power is delivered through an integrated 1.2m cord terminating in a standard 5.5x2.1mm centre-positive barrel jack. This common DC plug format allows direct connection to compatible development boards and hardware.
