Multiplus chatter noise. What is it?

Hi. My Quattro is tripping fairly often. When I turn it on it often develops a loud humming/chattering sound (I have included a link below to a recording the sound as I start up, then it trips after a short while). It's not related to load, as it happens when the device is isolated from the loads as well. Any ideas what it might be?.

I think it is from the top right of the box, behind the circuit board. The sound does not always occur. I can't find a pattern

Please make the sound file public.

From your description I think it is the power pack.

After hearing the sound I would say it's the power pack and your should get in touch with your dealer to ask for a repair/RMA.

How old is the device?
