Can you measure the resistance between the two wires? What size is the bed heater?
I measured 3 ohm and the size is 330x330mm.

@dc42 I have to correct my answer after using an other multimeter I get 1,3 ohm

That's a 12V bed heater. As you are using 24V power, you need a 24V one. That explains why your PSU was shutting down.

Is there a way that the heating bed can be used with 24V? Or do I have to buy a new one and where can I get a good one in that size?

From a little googling it looks like there is a Tronxy bed that is 24v compatible.
As for where you would be able to find it. I'm not sure about in Germany, but there's always gearbest. https://www.gearbest.com/3d-printer-parts/pp_314650.html

Sorry but this is a 230x230mm heatbed but I need a 330x330mm. It's 10cm to small.

@aimrabbit looks like you know the terms to google for then.

It's not that I'm tried to find one. But I only get undersized heatbeds so that's why I'm asking but if no one have an idea I have to find an other solution. And I'm don't asking just for fun... I'm asking because I'm stuck with the VIN problem from the beginning.
So I don't like your sacasm. -
My apologies, I didn't intend to sound sarcastic. It was just that a quick google search turned up several options in multiple sizes.
Here's a 330x330 24v: https://www.aliexpress.com/item/3D-Printer-MK2A-MK3A-Aluminium-Heatbed-Thermistor-Build-Surface-Sheet-300mm/32948965327.html

I bought now this one https://www.roboter-bausatz.de/833/mk2a-heizbett-300x300-mm because the one from aliexpress would take nearly one month to be send to me. But with your link I got the right model and found a lot of matches. Big thanks.

Sorry for not showing back for two weeks but I had got a lot of work to do.
What I can say about this problem. After I've got my 24V heater bed, the VIN is not decreasing anymore.
But now I got another problem which I realy not understand what to do and why it's causes.
At the beginning everything is fine and it's printing realy well but then after maybe 3-5 minutes the filament don't get through the hot end - if I pull it a bit back ( 1cm ) and then push it back in it will resume printing. What could that be and how can I fix this issue?
