Hello :)
i bought five elg-150-c1400b from Jerry (http://www.mouser.com/ds/2/260/elg-150-c-spec-740864.pdf), i wanne ask something about dimming.
This driver has Built-in 3 in 1 dimming function for B-Type (0~10Vdc or 10V PWM signalor resistance).

I wanne use a potentiometer 1-10v, is that possible? Because the driver has 0-10volt Vdc function, if i would use this potentiometer 1-10v would i destroy my driver or even my leds (cxb 3590)???

And if i would use a potentiometer 100k like this one Eaton Electric Potentiometer M22S-R100K (can i use this, is this potentiometer linear ???), could i dimm the driver from 100k to zero?
I would just need this Eaton Electric Potentiometer M22S-R100K(or other 100kpotentiometer which is linear) and nothing else?

if i look at datashet from driver, it should be possible to dimm this driver to zero without damaging the driver. but i wonder if it is possbile to dimm my cxb 3590 to zero too withouut damaging them.

4 x Vero 29's and a HLG xxxb
Regarding the dim function of the B variation:
I understand the two wires of the dim of the HLG should never touch each other. If I don't want full brightness, is it safe to put a 1/2W 10K ohm resistor between the two wires?

I am running a 100k pot and 10k resistor on a meanwell driver. And it has worked great for me.

Supra I posted the inside pix of the guts of a Mars@ driver as somebody asked don't recall who I put them on my perpetual mars hack thread

If a guy was to use an Meanwell APV 12-12 to run 4 CPU fans or even 4 mono stars.... can you WAGO connect that driver to lets say the power cord of a 185-1400 without blowing it up? I was wondering the same thing about a small bucking driver that could run monos? I see alot of people use old cell phone chargers, but I was wondering if this was another option to power fans or monos. Thanks

small PSU outta a old PC got your choice of voltage as wel 12v & 5v maybe another ?v depends on pwr supply .

just a thought , i think i seen a build with one

Yes that will work great to power fans. I should used those instead of my wall warts which costed more lol. I paid like $6.95 and those are about $5.80 if not less.

Thanks for replying....I'm looking to avoid using a phone or computer charger cable to power my fans and some monos. I'm wondering if I can connect the APV to a HLG power supply using a WAGO connector without any problems? I have the same question about connecting a bucking driver to a HLG using WAGO connectors? So in other words.....One 3 slot WAGO connector with HLG power (+), APV (+), bucking driver (+)... and then another 3 slot WAGO connector for all 3 drivers (-). Thanks

I don't think it's a goof idea. You're complicating it for yourself. While it's possible to power APV from HLG-185H-C1400 (as long as it's output voltage is >127V) it doesn't make much sense. It would be better to power APV directly from the mains and then a buck from APV. I'd consider using separate APV for fans and APC for monos.
BTW if you wire it the way you described, you'll blow the buck driver.

awesome info as always

a\I have a similar question

Im going to power 2 cxb3590s off 1 ELG-150-C1750B


so at that current I have some volts left over and was thinking to add some monos
can this be done assuming the monos will handle that current(dif voltages on the same string?)?

should I use a bucking driver off the ELG for monos?

or should I connect a bucking driver to the driver for the fan?

thank you for all your hard work and help

Thank you for replying.... I truly thought I was simplifying things by connecting 3 drivers into 2 WAGOS and having only one main 14 gauge power cord to the wall. I was concerned that the smaller APV, APC, bucking drivers couldn't take power straight from the wall like the HLG can. Thanks to you I know the bucking drivers cannot. I wanted to use a bucking driver due to it being way more efficient than the APV or APC, but I'm going to scratch it now that I know it will not take the power from the wall without blowing. Thanks again!!

If I understand ALESH's response to my question correctly you can add a bucking to the power of a Meanwell APV 12-12, but you are better off using a APV 12-12 for your fans and a Meanwell APC 12-700 for the monos. A bucking driver off the ELG will blow. You should have 14 extra volts left to max your driver after running the two cxb3590 36v. From the research I have done I haven't seen any monos that can be run as high as 1750ma that the ELG you have runs at.

general question on wiring , can you use solid wire between cobs & then use stranded for the rest of a build ?
all the holder I seen the solid would just be easier to work with being stiff & you don't need as many attach points
Do know it's way easier to push solid wire into the solderless holders you have to tin the stranded shit or risk a single stray strand of copper & lotsa AL around
