Anybody tried the ELG version of Meanwells, Rather than HLG...

I've got an elg-240-c700b and all the leads are blue/brown (input, output and dimming).

I've also got an older elg-150-c700b that has red/black on the output and white/blue for dimming.

somebody else said these were performing over spec at 115V input.

my first elg-240-48A is putting out 5.5A with 2 cobs(@53V -> ~ 290W) w.115V input

i just built a new 9-banger cxm22 3000k 90cri light for a 3x3 tent (overkill yes but it goes with the territory ) and will light it up with the ELG - should be super efficient with 9 cobs at 600 mA and have great coverage. ill test it at both 115 and 230V input

3 things i dont like about these:
1.dimming screws are on the back

2.there is no ground lead, you have to physically ground the case which is a little less elegant than tossing a simple cord end on. it can be made pretty with a ground lead and some heat shrink tubing i suppose.

3. both input and output leads are blue/brown. too easy to mess up i like red and black for dc side color scheme. i dont wanna find out what happens when you land 230V ac to the DC outputs

I ordered a couple of these over the weekend. Could you perhaps explain how to operate the voltage & current adjustment? I see that here are two controls and that it can be used in both constant current and constant voltage modes. I assume you were running it with the cobs in parallel considering the forward voltage and that it's the 48A model, right?

i have 48A and 48B to test

yes you need to run parallel unless you have 12 or 24V cobs

A models adjust voltage and current, if your cob array can handle it i just crank them up which should deliver higher than any driver in that "elg240" class if it works like the HLGs

dont hook up just one or two cobs or you'll blow them up

I ordered a bunch of 1818s from you, would 1 driver per 2 leds be overkill, or rather, do I need to worry about screwing things up if they're set incorrectly? I'll be putting them on some prettygood heatsinks, so heat should definitely not be an issue.

Thanks!!!

depends on the driver, they come in all sizes

Ah, I meant the ELG-240-48A with 2x 1818s

you can but they'll top out on voltage @ 110Wea. 3 would be better on that driver you'd get close to 90W each

Would it be dangerous to run 2x on a ELG240-54A? I've read some cautioning about running cobs in parallel, but I can pick up the ELGs for almost half the price of the HLGs. Also could I pester you to maybe explain how the 2x adjustment points work? Would it not be a matter of either controlling the voltage OR the current? I see the A models have two holes for adjustment.

Thanks J

you simply adjust the voltage down with the screw, all you need is a meter

Any more info on these Bobby? Do they pretty much perform like the HLG's?

ie. If I'm going to run 4x cxm22 on an ELG-240-48, I'll want to get the A version?

they work the same. and puts out quite a but more at 110V input than the spec says

things i dont like about them (minor):
adjustment screws are on the back
has a 2 wire power cord. its a hassle to ground the frame separately to a 3-wire cord

Know its an older thread, but better to collate info on one page.

I am also considering ordering ELGs as there is a waiting period for the HLG line in 240W at digikey

I was thinking 3x4ft dbl row at 1.666A totals 4.998A
Not sure if I should take the 42 or the 48V unit. We used 42s on the COBs and ran them with the voltage wide open.

Datasheet says 39 to 45V for the 42V and 44.8 to 51.2V for the 48V one

Samsung calculator says 44.9V at 95C, 45.1V at 65C and 45.3V at 25C for the fixture I am planning.
I'm afraid the 42A might not keep up if it gets cooler and the 48V might overvoltage them. I want to use the B type with a simple dimmer pot.
I want to run the driver as close to 100% as I can.

Any advice? Should I just settle for the aggravation of the dual trimpots for safety on a 48?

The only difference I could find between the HLG and ELG in this size is THD distortion, being about double on the ELG model at about 11ish%

In your case I would use the 48b version. slightly more efficient than the 42V and voltage will be capped very close to 48 volts.

plenty of hlg-240h-48b drivers available

Unless they do free shipping for larger orders, they are off my list.
Looked at mouser too, but they are more expensive than Digi

Anyway thanks for the input. I've never even turned my 320W 48 up all the way. It works out quite a lot more money though when doing 320W drivers rather than 240W.

arrow has free shipping, sometimes a decent price.

AFaik the 42 volt B version will be capped close to 42V, you won't get the voltage range without the A version.

Yeah, you are right. Shit is easier to think about when the morning and afternoon stone has worn off.
It is just such a schlepp if I order the wrong shit as I am in South Shithole.

Will check out Arrow, never used them yet.

You reckon I should skip the ELG version? The price is very attractive.

if cost is a really big deal the elg b version seems to be a good choice. I'm running some elgs on very low cost light bars (strips on 2" wide aluminum channel).

i dunno about arrow's free shipping to south shithole. But lots of vendors and price points to choose from.

Will do, I'm just in the middle of potting up some small plants that are getting root bound, as well as fighting with the kitchen sink plumbing. Replaced everything from the hole down, but the damn pipe from the wall is too short to seat properly. I'll cut it down and extend it. to the correct length, I just need an extra inch.

www.mouser.com has good prices on Mean Well drivers.

They have a bigger range of options yes, but prices are higher for all models I am looking at.
