Driver questions, Mean Well A/B versions and voltage/power/dimming

I'm about to order MW ELG driver and I'm not sure if I understand all the differences between A & B versions.
A version lacks the 3in1 dimmer that B version has but there are manual regulators on the unit.
Are these regulators on the main unit of A version regulating both output current and output voltage?
If the manual regulators are missing from the B version is it possible to regulate current and voltage output on the B version?
The 3in1 on the B version is only for dimming by voltage regulation?
How does dimming works with LED drivers? Voltage drop or current also?

Furthermore, if the current cannot be regulated on B version, does the B driver always output full current? Is the current then evenly distributed to the number of LEDs?

As example, I'm planning to use the ELG-240-36B version. If I understand correctly I can dimm the lights (V) with the 100K potentiometer, but i cannot adjust current A?
If I connect 5 COBs to this B driver, will each COB receive 1,335A (6,66/5) . If i connect 8 COBs, will each COB then get only 832mA (6,66/ or do i risk damaging the driver by overloading it? Is the current scalable to number of COBs or do i risk of overloading the driver if i connect more COBs?
All COBs get same voltage by current is divided by their number?
The COB's i plan to use are rated at 1170mA but span from 585-2340mA. Does this mean that i could connect 5 COBs and they will share the total current of the driver, and if i connect more COBs they will still work but at lower current and output, while fewer COBs will be "overpowered"?

Is A version more versatile than the B version? I cannot get the A/B version as they are not on stock at my supplier.

the 3in1 dimming circuit of the B version sets the current... which directly influence the voltage.
you can connect 5 or 8 Cobs, the current will be divided as you wrote, no damage to fear.
the A version would allow you to overdrive the driver as you can directly infleunce the setting for voltage but you wont be able to dim that low as a B version can.
maybe you can get a AB somwhere else?

Remember to not run elf series on 120V, they will get downgraded output. HLG and XLG are ok (and XLG tends to come as AB: both onboard and off board dimming )

Dimming is the same thing as current adjustment.

Fantastic support, thanks!
I'm in Europe on 230V so it should be safe to use the cheaper ELG series.
Seems that A version is preferable over the B version as the current and voltage can be adjusted on the unit.
Is it safe to assume that B version is set to 36V default and V can only be lowered by using the 3in1 dimming function?
I would prefer the A version as i would like to option to adjust current and voltage.
Btw, i found this video on YouTube explaining a lot of my questions. I should have done better research before asking.

Again, thanks all for great support, hope to be able to support others in the future!

B-version will not do any voltage control, even with an attached dimmer. it will only control current, but from very low, maybe even dim to off, i cant remember. I like the a-version as you can set a ceiling for how much current you send per cob.

The XLG-240-h-ab is a good match here; it will do any voltage between twentyseven and fiftyfour volts, and has both onboard and off board dimming, and is a bit cheaper than the hlg. Still id say the hlg is better quality, runs colder, and for a piece of gear that youll be using for a long time, seven year warranty, its well worth splashing out those extra ten euros or so for the hlg.

Thank you so much for this recommendation, it's also on stock at digikey where i will be ordering some other stuff.

@Rocket Soul , how does one adjust V on the XLG? By using the 100K pot on the 3in1? What do i need more to be able to set the voltage on HLG-240-h-ab?
