Where to find 230V - 24V transformer
chiken:
What do you guys where i could find 24V (min. 3A) transformer,
i've been salvaging quite a bit and repairing some stuff,
but i did not really encounter a 24V transformer, or am i missing something?
(EUROPE)
james_s:
24V is often used in industrial controls. Sometimes you might find a 12V transformer with dual secondaries you can wire in series. If you're willing to buy new then 24V is readily available, guy could also look on eBay for local items.

For my current bench supply project, I bought this transformer from a local Jaycar store. The same thing might be available in your country also.

Although it can be configured for 24VAC, I'm relay switching the secondaries for parallel 15VAC or series 30VAC.
Keep in mind that a derating factor needs to be applied when the secondary output is rectified and filtered. I'm expecting that my project will safely supply 4 amps on its low voltage range and 2 amps on the high voltage range.
EDIT: I just realized that the primary is 240VAC for this transformer.
Jwillis:
Transformers are quickly being replaced by Switch mode power supplies.Especially in Europe (as I understand) because their not as efficient as a SMPS. So finding them In the junk pile is getting harder.
Benta:
I cannot imagine anyone having a problem finding a 230/24 V, 3 A transformer. It's one of the most common sizes around, plentiful everywhere.
You're looking in the wrong places.
