Is it possible to get + - 30v from this?
It has double outputs but can one be used as a negative out?

Yes, there is a switch to series connect the two floating 30V supplies, and you use the middle red and black terminals as commons.
Then the leftmost black=-30V, the rightmost red=+30V, and the middle red/black=common. The greens are chassis grounds.
You can also parallel the two 30V supplies for twice the current. There's also a separate 5V supply.
We've purchased a number of these models, and they seem ok for the price.

Just bought 1 from the german seller,are you sure about the 19% Vat when it´s within EU?

 

[Ryssen]

I see they are selling this one in Sweden to but the shipping is about the same so...they might still send it from abroad.

I recieved the PSU today and it is promising.
And there was no extra Vat.

Keep an eye on these PSUs, this model is known for having a turn-on spike. It was fixed in a later revision by the OEM but not before at least 90% off the supplies had already entered various channels in the market.

What to do about it?

What to do about it?

All you can do is disconnect your circuit when you power the service on, if I remember correctly.
