Regulated 12V 1A AC-DC Power Adapter with 5.5x2.1mm Plug

This regulated AC-to-DC power supply delivers a steady 12V DC output at up to 1A via a standard 5.5x2.1mm centre-positive barrel connector. Fitted with an integrated 2-pin EU mains plug and a 1.2-metre cable, it plugs easily into standard wall sockets. It is well suited for learners, makers, and hobbyists needing reliable power for their electronics and robotics hardware.

Stable voltage output

The adapter supplies regulated +12V DC with a maximum current of 1A and low ripple and noise of 150mV peak-to-peak. Line regulation is kept within +/- 1% and load regulation within +/- 5% for dependable power delivery.

Mains input and connection

Featuring an integrated 2-pin EU plug, the unit accepts wide-range mains input from 100Vac to 240Vac across 47Hz to 63Hz frequencies. DC power is output through a 1.2m cable terminated with a 5.5x2.1mm centre-positive barrel jack.

Efficient power usage

With a standby power consumption of at most 0.1W when unloaded, the adapter minimizes phantom power draw. Maximum input current is rated at 0.3A under full load at 90V/60Hz.
