This small power supply, measuring approx 4.5 x 3 x 1.5 inches, is an excellent choice for various projects requiring 12 volts DC. It can be used for low voltage lighting projects, as well as any other thing that is normally battery powered, like automotive accessories. It will provide up to 5 amps of current (60 watts) @ 12 VDC. We use this power supply to provide power to our LED under-cabinet kitchen lighting. It works very well.
