I just purchased something called a Skybell and I am trying to get it wired up. Looking for Crossy or one of the other electrically savvy people to help me out.

 

The specification calls for a 12vdc 10va transformer. I understand about the 10 ohm / 10 watt resistor, and have it already.

 

 

 

My question is this: Is there a specific 12vdc 10va adapter I need to look for, or can I use a generic 12vdc adapter, and then the required in-line 10ohm resistor is what takes it down to 10va? How many amps should the transformer be? surely not 10 amps?

 

Thanks in advance.

12V, 10VA is about 900mA so a 12V DC 1A supply would do the job just fine.

 

I would get a decent quality one, possibly a baby switch-mode jobbie from NPE, more expensive but infinitely reliable.

 

 

Outstanding. Much obliged for the info.

In an alternate timeline, it seems your doppelganger also asked this very same question a year ago on Redit:

 

 

Yes indeed- but you fail to notice that nobody gave him a sufficient answer to the question. I knew that Crossy and / or the others here would provide the expertise in a sensible way.
