I have a dimmable electronic transformer .
240V in, 11.4v out, 5A
Can I use this for an LED outdoor strip that requires 12 V. 5A

I think you will find the transformer might need a minimum continuous
load before it switches on. If your led strip has any on off effects you
might have problems.

LEDs are DC

Or the OP is using the word "transformer" in a generic way to mean a
device that "transforms" mains to something else. These days lighting
"transformers" are far more likely to be a switched mode power supply
that a lump of iron wrapped in wire.

We really need full information from the OP about the "transformer"
they have.

This on the back of the transformer: EN-SC60
Prim 240v-50/60Hz, 0.26A
Sec: 11.4v-eff,5A
Cos 0 = 0.98
ta:50C tc 75C
1.5 surge protection ENS 1547+a1

20-60w/va

Is it an "Enlite"? If so the spec sheet says AC output

Are the outputs marked + and -?

Yes it is an enlite. I guess that hits that one on the head with AC output.

If you are talking the output wires there is no indication just 2 wires
come out of the transformer both coloured black.

Definitely a transformer, not a power supply
and you can't drive leds with it directly.

Much will depend on the above (although I suppose you could rectify the
output if AC)

The VA on the last bit suggests an AC output.

Likely not DC then - do you have a multimeter?

Thanks all for your help, I wont mess about with it, I`ll maybe pick
something up on ebay.

LV lighting `transformers` usually fairly high frequency AC...

RS, CPC/Farnell or Rapid for a U.K supplied CCTV 12V D.C. power supply.

Some frankly scary as **** knock off PSUs around, seen a few , had a couple go bang, now only use and spec ones that come from reputable supplier, i.e.

If it is made for low voltage halogen lighting, probably not. Unless the
LED strip is made to run from AC.
