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 .
