A transformer unknown to me in the kitchen

Hello, I bought a house and in the kitchen the 3 halogen spots above the countertop keep going off. I have checked everything and it seems to be okay. Presumably the transformer just switches off. I would install a new one, but unfortunately the wiring is behind the wall cabinets... Planning in 1998 was not that foresighted. The transformer makes me curious and I can’t find anything about it online. I would like to replace the halogen lamps with LEDs. However, I cannot find any watt rating on the transformer indicating the "range" I should stay within. I took a photo of it. Can anyone make sense of the information?

It's all written on it:

11.5V at 2.6A
P = U*I

so 29.9W

it's also written above as 30VA (Volt Ampere = Watt)

11.5V is a halogen transformer. You can easily connect all 12V LEDs to it. But if the transformer already shuts off due to overheating, better replace it. 12V LED transformers are almost given away on Ebay... For LED strips you need a bit more depending on the length, rather around 50W+. So depending on how densely equipped and which chips: 10W/meter as a guideline.

If not here, then surely at the manufacturer. Just give them a call 05223-185-0

Thank you for the reply. I would like to replace it, but I would probably have to dismantle the wall cabinets for that. The cable disappears directly behind the transformer. I would like to avoid dismantling that. But now I know where the overheating comes from. There are 3x 15 watt bulbs in there. I'm surprised that thing even turns on... I'll first replace the bulbs with other ones.

There is, however, a "small" problem. The transformer provides alternating current and LEDs require direct current. The sockets will also be different, for good reason.

Oh, I see. Good to know, thank you. Then I have to rethink. The cable that supplies power to the transformer is indeed "his," meaning permanently installed in the transformer... But in the end, it doesn't matter if I simply cut it and connect a more modern transformer to the cable, right? Under the insulation, there will only be positive, negative, and ground anyway!?
