Would need a 30mA DC supply ... 12-24V

Anyone know of small low cost DC supply modules ? ..........

Tons of plug packs on ebay and amazon and aliexpress.

I have a draw full of psu's ... laptop, router etc, I could use one of
those but as it only needs 30mA something small will be easier to house in
an existing box.
