Ambika Power supply

#1

Does the Ambika only works with an AC power Supply?
Ambika is done, but no Power supply available. Too bad. :frowning:

#2

yes itā€™s made to work with AC only (without modification). you donā€™t have a transformer so you could at least try it?

#3

9V AC ; 600mA at least

#4

Thats the problem. I throw them all away. I thought ā€œIā€™ll never use themā€.
I have a transformer here and built one at the moment. Problem is only ~15 Volt.
Is this a problem ? Normally only the Regulators should getting a little bit warmer.

#5

Warmer yes, ā€œa little bitā€ no. I donā€™t recommend 12V AC, so 15V AC will make them scorching hot. If you have only one voicecard in placeā€¦ maybeā€¦

#6

I see, I must order one.

#7

Any recommendation for where to find a good one by the way ?
Iā€™m struggling to find anything with more than 500ma and a 2.1mm barrel connector.

#8

i was recommended one here on the forums a while ago, works fine. you should find it with a quick search.

#9

Some references here

Thank you.
Actually Iā€™ve also just found this one for UK and Europe:

I recommend the Henri Electronic one. If you insist on feeding 15v heres a tip: Plexi smells a bit like garlic when it melts, just a moment before it starts to burn.

#12

Would that one work?

(Iā€™m not even sure itā€™s a power supply lol)

#13

No, wonā€™t work, this one has DC output.

#14

ok, thanks. Should I conclude that there is none at Mouser, otherwise you would have provided a ref, thatā€™s it?

#15

Someone has found one, but I donā€™t have the ref.

2 items, but only for north america, 120V input :-/

#17

Maplin do an adjustable-voltage AC PSU, if youā€™re in the UK. Works fine for me. Only potential downside is it has a super-bright LED on it (mine does, anyway, though the photo on the website shows a red one).

I didnā€™t find anything for UK or Europe on Mouser.
The only one meeting the specsIā€™ve found with a UK plug is the one from Rapid that Iā€™ve linked above.
@toneburst that is 500ma though, pichenettes recomends > 600mA

#19

so this one is the one I need ?

Actually, the output current is too weak on this one.
