Description
This regulated AC-DC power adapter supplies a stable 5V DC at up to 1A via a standard 5.5x2.1mm centre-positive barrel plug. Operating across a wide 100V to 240V AC input range, it provides clean, consistent power for electronics projects. It is an ideal, dependable power source for learners, hobbyists, and classroom workstations.
Stable regulated power
The adapter delivers a constant 5V DC output with a maximum current of 1A and low 150mV peak-to-peak ripple and noise. It provides reliable operation for low-voltage circuits with zero minimum load required.
Wide mains compatibility
Featuring a standard 2-pin EU mains plug, the unit accepts input voltages between 100Vac and 240Vac (ranging from 90Vac to 270Vac) at 47Hz to 63Hz. It also features low standby power consumption of 0.1W maximum at no load.
