Description
This UL-certified 12V 3A 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 3A at a near-constant regulated 12 VDC, even when no load is applied. This power supply works with input voltages from 100 to 120 VAC (60 Hz).
The AC Input power cord is 2′ (~60cm) long and features a standard 3 prong North American plug. The DC output cable is 6ft (~2m) long and terminated with a center-positive, 5.5 × 2.5 mm barrel connector. These are NOT compatible with 2.1mm DC Barrel Accessories.
