Delta DPR 3000B-48

I just bought two Delta DPR 3000B 48V
3kw 96,2% max efficiency
41x82x265mm 1,3kg
42-58V programmable output, the value can be safed in the rectifier.

But I do not know how to programm them right now. I have nothing found in the internet about Delta and CAN.

I also ordered a controller for the older delta rectifier version hoping to get the CAN codes from it.

The Delta is the one on the left side. Middle Vertiv R48-2000E3, right Eltek Flatpack S



I also tested them with an electronic load.

61A at 50V 3050W
61A down to 40V
From 39-20V the current drops linear to 51A. It runs even at 10V.
Fan speeds up under 48V.
With 2000W at 53V it runs very quiet.

The Delta PSC 3 system controllerhas arrived and I can change the output voltage via can bus. But it is not a permanent change and I did not find out which ID and which code does the voltage change.
Everything from the can code which looks like voltage, does not work when I send it from my USB-CAN converter.

Probably it is similar to the Eltek Flatpack and you first have to login to bevor you can send changes to the adresses psu.
