Details for item #1774

This UL-certified 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 3 A at a near-constant regulated 12 VDC, even when no load is applied. The DC power cable is 5 ft (1.5 m) long and terminated with a center-positive, 5.5 × 2.1 mm barrel connector that 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.
