Linear kit start/stop curve
Start — pretty slow, but who cares?: Current limit engaged — just shorted 🙂 Now quick enough: A little overvoltage after current

Lab (or pseudolab for DPS5015) PSUs 3.3v power-up
Small comparison.
1.5KW HF load SWR
Big HF load
It’s based on a copper plate, big old whipped aluminium radiator and two 100Ohm resistors, 800watt each.
