I have frequent needs for a 5VDC for VIN when 24VAC is very available. About 1500mA would be adequate (Electron/Photon with some relays), but a bit more would be nice. I’ve found a few offerings via Kele and Dwyer, but I’d much rater have an efficient circuit that I can put on my own board. Any suggestions or if you can point me in the right direction, it would be greatly appreciated. ---

@mikemoy, close, but no cigar. This appears to be a DC to DC voltage regulator. With all the tiny 120VAC to 5VDC USB adapters around, it’s amazing how hard it is to find a 24VAC to 5VDC adapter. Thanks! ---

I don’t know how that happened. I was looking for the 24vac input, must have clicked on the wrong one. how about this one. > **[Car LED Waterproof DC (AC) / DC Buck Converter 24V 12V 36V (8V-40V) to 5v 1A 5W ...](http://www.ebay.com/itm/Car-LED-Waterproof-DC-AC-DC-Buck-Converter-24V-12V-36V-8V-40V-to-5v-1A-5W-/152481164253?hash=item238095ebdd:g:0dYAAOSwWxNY0fpj)** > > Note: The color of the item may vary slightly due to photography and your own computer > Feature: > Overcurrent protection > Short-circuit protection > Waterproof design > Waterproof full-potting > Specification: > Power Model: XW-AC24-DC5-15W > Input... ---

@mikemoy…thanks!!! I ended up using this reference to find a 4A version on newegg for about $7 and ordered a few of them. If the output power is clean enough for Photons and Electrons, this will be a huge benefit for the HVAC applications that I typically put in place. Again…THANKS for the recommendation! ---

Huh, That’s great, never would have thought newegg handled things like that. Good to know. ---

Amazon (DROK) has these: [https://www.amazon.com/gp/product/B01DBQP7OS/](https://www.amazon.com/gp/product/B01DBQP7OS/) I bought some to get 5V from my 24V 3D Printer. Kenny ---

@Kenny - thanks for the suggestion. It appears that’s a DC to DC converter and I need something that will accept 24VAC input.
