Power Supply

Perfect power supply for my project. Hooked up 15’ of LED tape, 2 PIR sensors, a dimmer, and a fade in/fade out. Wire diagrams provided for the power supply were very helpful.

Burned Out in a Year

I bought this power supply in September 2019. It went completely dead on me 12 months later :-(

It was outside powering LED lights but was not exposed to direct sun or moisture. Very disappointing considering the cost.
