Oznium's efficient switching adapters are available in three convenient amperage's to suit your project needs: 2 amps, 3.25 amps, and 5 amps.
2 amp = 1-3/4 W x 3-1/4 L x 1-1/8 H
3.25 amp = 1-3/4 W x 4-1/2 L x 1-1/4 H
5 amp = 2" W x 4-1/2 L x 1-1/4 H
Which amperage is right for me?You first need to figure out the total amperage draw of your LEDs. Suppose you are powering 16 feet of our LED Ribbon Strips which use 130 mA per foot. Note: mA is an abbreviation for milliamps, and there are 1000 milliamps in an amp, so 130 mA = .130 amps
16 feet x .130 amps = 2.08 amps
While the 2 amp AC Adapter would work for this application (16 feet of LED Ribbon Strips), it would be at the limit of its capabilities. The LEDs may not reach their full brightness potential, and the 2 amp AC Adapter may work harder than it should. In this case, it would be better to go with the 3.25 amp AC Adapter.
