Wall Power Adapter: 12VDC, 5A, 5.5×2.1mm Barrel Jack, Center-Positive

Details for item #1468

This UL-certified (file number EPBU.E477038), desktop-style AC-to-DC converter gives you an easy way to power your DC electronics project from a US-style AC electrical socket. It uses a switching regulator to efficiently output up to 5 A at a near-constant regulated 12 VDC, even when no load is applied. This power supply works with input voltages from 100 to 240 VAC (50 to 60 Hz), which makes it compatible with all standard international mains voltages and frequencies.

The adapter includes a 1.5 m (5 ft), removable AC power cord that is terminated with a three-prong, US-style plug, and it has a non-removable 1.5 m (5 ft) DC power cable that is terminated with a center-positive, 5.5 × 2.1 mm barrel connector. The barrel connector works with the DC power adapter barrel jack and the DC barrel jack to terminal block adapter. It also works with the barrel jack on many Arduino boards and our Arduino-compatible A-Star 32U4 Prime controllers. This adapter has a green LED that indicates when it is receiving AC power/mains electricity.
