Hi All

 

Can anyone recommend a 12VAC 2-3A power supply module to power solenoids?

 

I need something with a 240VC input and output being 24VAC, it must be with wires, as I do not want to solder it on a PCB.

 

Another key requirement is something small/ thin, if possible. 

This topic has a solution.

Thanks

Regards

DJ

Title & later in the OP say 24V - so which is it?

Chassis mount ?

 

Open frame ?

 

Plug in / wall-wart ?

How small is "small" ?

 

How thin is "thin" ?

  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected

We require something that ideally be be fixed to a DIN RAIL, otherwise we simply using some cable ties to fix it.

 

We would like something like HDR but can not seems to find an 24VAC output version.

This could work,  looks small as well.

Thanks

So why did you not mention that??

For an AC output, all you need is a transformer - not a "power supply".

Sorry, my error, should have mentioned transformer.

Transformer is probably easily surmised

should have mentioned DIN  

Why do you give the facts later?  Is someone prohibiting you from providing the details--why?

Tell them they will get your quicker action when all the facts are provided!

Indeed.

Indeed - this is not the first time!

It's a bit depressing that a 24VDC@2A power supply (SMPS) is so much smaller and lighter than a 24VAC@2A transformer :-(

Easily resolved by increasing the mains AC frequency to hundreds of kHz. You can use tiny transformers then. Of course, there may be other issues... :)

I wonder when it will become "obvious" to follow an SMPS with a 60Hz (120Hz?) chopper/bridge/etc.  Might be soon!

Just use DC , AC not required (if DC is readily avail)
