Folks,

Need constant current supplies around 3A, voltage range to be tolerated should be 16V-21V or wider, outdoors, weatherproof, UL. The Meanwell HSG-70-24 is a few volts higher than we need but would have worked nicely:

The problem with them is sluggish to no responses from the factory and 7 week lead time mentioned at the few distributors there are. That's no good because we need several hundred by latest end of April.

Does anyone know other sources? Probably from the direct LED drive market. Should not be much over $50 in 1k qties.

We'll just use oversized units for a while.

Your problem is solved, but I'll note that I've had good support from PowerGate.

We could not get help there. But at TRC we did, hoping that a couple hundred units from them are enough to tide us over the leadtime until new ones arrive.
