AltronixSMP3 6 12 OR 24VDC @ 2.5 AMP, PC Board, Switching Power Supply Charger

I have two of these boards that have been powering graphical alarm/automation keypads with battery backup for about ten years now. I originally bought from a specialty house and saw them on Amazon so wanted to give them the credit they deserve. Opted to replace battery’s twice now since the boards went into service but the boards are still going strong and I expect I’ll get another ten years.

Works for my application, i.e., burglar alarm system. But bought when the price was still reasonable. Nowadays, not so much!

Unit so good I bought this second one
