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

I've seen photos of ELGs with earth wires - does anyone know if they're now shipping with three-wire AC connection instead of two?

Yes for CV drivers they have 3-Y at the end and for cc drivers they are ELGT-

 

[Prawn Connery]

Thanks. What about the ELG-C series?

They have a different type number when it's with 3 wires.

:edit: It's when there's 3Y at the end of the product code. See: https://www.meanwell-web.com/nl-nl/ac-dc-single-output-led-driver-cc-with-pfc-3-wire-elg--100--c500--3y

 

[diyled]

As above. For the C series it's elgT-xxx-Cxxxx .For the CV drivers its Elg-xxx-xxa-3-y.

The C series has a 3y version too but my supplier doesn't stock them.

OK, thanks for that, but the model I'm after (ELG-200-C-1750A) doesn't seem to have those numbers on any of the sites I'm looking at. Does meanwell-web ship to Australia? I've only ever bought HLG drivers and they have all been earthed. I've emailed Mouser about the earth wire, but no reply yet.

I just noticed Arrow says they're "4 pin" - which I assume is two wires in (no earth), two out: https://www.arrow.com/en/products/elg-200-c1750a/mean-well-enterprises?utm_campaign=arrow_findchips_2018&utm_currency=&utm_medium=aggregator&utm_source=findchips&utm_content=inv_listing

Mouser doesn't list anything that I can see: https://www.arrow.com/en/products/elg-200-c1750a/mean-well-enterprises?utm_campaign=arrow_findchips_2018&utm_currency=&utm_medium=aggregator&utm_source=findchips&utm_content=inv_listing

Neither does Digikey, but they don't have the "A" model I want: https://www.digikey.com/product-detail/en/mean-well-usa-inc/ELG-200-C1750/1866-1523-ND/7702978

If after the c1750 is blank its 2 wires if there is a -3y its 3 wires as per meanwell datasheet

Thanks for the link to the manual. I guess I need to look for an ELG-200-C-1750A-3Y

You can buy one through the link I provided, not sure what their shipping is like.

 

[wietefras]

Personally I couldn't find a "3Y" B driver (on stock) either and bought the 2-wire "A" version for a small veg fixture. Bolted the driver onto the frame and simply connected the frame to the earth wire inside the "wiring box".

 

[Airwalker16]

I did that exact same thing....didn't read enough of the data sheet, although its still useful if I understand this correctly...
I ordered the ELG-240-C700A expecting 343 forward volts, so running it on 110v input, the forward V will actually be 257 right????

EDIT: Yes, ill answer my own question here, its written in plain English on the case of the driver.... I really need to SLOW DOWN and READ while researching this stuff ......

That was funny. So are you saying you can pull 343w from an HLG240 on 110v?

 

[Airwalker16]

I STILL don't understand how to match up the 240-36/42/48/54 compared to CC HLG240-700/1050/1400/1750/2100. They're made to run cobs in PARRALEL ONLY right?

Yes, they are made for paralell connection. I prefer the A version cause you can adjust the voltage up or down, getting 50V cobs on a 48, or alternatively adjust voltage down slightly to make sure you dont don thermal runnaway if a chip failed.

So wats the difference between them and how do you use a cobs fV to determine what one to use and how do you know what mA youre at?

 

[Chip Green]

The driver will have a total amperage available, say 10.2 amps for instance....The current coming out of the driver is within a certain voltage range only, say 24v... v (+ or - adjustability on the A versions)....
If you hooked up one 24v emitter, it would have 10.2 amps at 24v and it would burn up...
So you need to run enough emitters, to divide up that amperage into an acceptable range!
10 x 24v emitters in that case would spread that amperage between them and each would run at 1020 ma.....

 

[nfhiggs]

No, that is not correct. It does not work that way - not with CV drivers. The 24v emitter will only draw current according to its VI curve. F-strips for example, at 24.0 volts will pull about 950 mA, and at 25.2 volts they will draw 1.8 amps. The only way for it to draw 10.3 amps is for the voltage to rise considerably - upwards of 30 volts.

 

[Airwalker16]

So what does the 36/42/48/54 numbers represent in line with cobs and how any on each type of drivdriver?

 

[Chip Green]

Okay! Thanks nfhiggs, something I was a little unclear about evidently....

 

[NothinYet]

The only way for it to draw 10.3 amps is for the voltage to rise considerably - upwards of 30 volts.

So a strip will only pull as much current as the max volts of the chip or the driver with 1 hooked up to a CV driver?

If you look at the spec sheets the constant voltage drivers have a range of voltage they run at. Example a 42 V driver may be able to run between 38-45v depending how many amps that driver puts out, and the wattage the driver is rated for.
