New FNIRSI power supply.
Fungus:
I was just throwing thous out there. If you need a portable power supply then this thing could work nicely if you find a power bank with better support for USB C power delivery.

Here is the hacked protocol: https://github.com/jcheger/fnirsi-dc580-protocol
tai:
Great! I tested the serial port on my new FNIRSI DC-6006L power supply, and can confirm that it also follows the same protocol except that it first responds with "KB" instead of "MB". Other than that, it seems the protocol is compatible.
tai:
Based on the work for DC-580, I wrote a CLI tool to control similar model, DC6006L.

I can't comment on DC-580, but serial port output from DC6006L is a mess as its output format is a mixture of different frames that are quite identical and don't give much information on what it contains. It's also not compatible with DC-580. So far, it works for me, but your milage may vary.

Interested in how much switching noise is on the output unloaded and loaded of the DC-6006L. Much appreciated if someone could post a scope trace of this.

I only have a 10MHz scope and a 20V PD charger. For what it's worth:
Test setup:
Two x1 probes with 50Ohm termination into Pico 2204A. Power supply connected to two 6Ohm resistor in parallel.
Measurement at 18V no-load:
Measurement at 17.22V 5.57A:
