This UL-certified (file number EPBU.E477038) 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 9 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. This particular adapter also works well with many Arduinos and the BASIC Stamp discovery kit.
We have wall power adapters available in a range of voltages and maximum output currents:
