TKXEC DC DC Buck Boost Converter Variable Voltage Regulator CC CV 0.5-30V 4A 5V 6V 12V 24V Power Module Adjustable Voltage Regulated Laboratory Power Supply

Q: If battery powered, what level of Peak-Peak output voltage ripple/noise should I expect with mid-range operating conditions?

There is a high frequency (<100kHz) noise on the output depending on your current, the output voltage and the supply voltage which is arround 200mV pp. Most devices are not bothered by this ripple but if you are close to a receiving antenna for a radio you might experience interference. Some ferrite cores and a 1000uF capacitor will work wonders.

Q: Is there some function that allows one to disable or lock the rotary knob so that it cannot change the voltage once the desired voltage has been set?

The rotary knob is a screw not a knob. Once you screw in the desired voltage it will not change. Put some tape over it if you’re worried.

Q: Does this unit generate rfi at hf frequencies?

It depends how close the unit is to your receiving antenna. If your antenna is outside and the device inside you shouldn’t have any problems.
