Hi BOBBY_G,
do you also know if meanwell has plans to release HLG-600H-C series?
Greetz!

I would wonder. That would be some real high voltage honestly. Yikes

That could be a great driver for some of the Citizen COBs that run over 100 volts, same with the 320.

Great news for those that want to play with some high voltage. CDIWeb has a large selection of the HLG 320C in stock. I will talk to Whit and see if he can do a discount code. For us their is https://led.cdiweb.com/Products/5 It is less confusing than their standard site. There is also a tool for the Citizens. Let me know if it works, I don't have accel.

I thought the "C" models kept the current the same no matter the # of cobs?now thats some current!!!!
can run 3 3590s @ 2.8A/104W each
4 @ 2.1A/75W each
efficiency leaves a little to be desired tho

I dont see many available on CDI. I did talk to somone at a different distributor and they will sell them for $100 shipped. I ordered one of the C1750B models. They are currently backordered about 1 month tho.

CDI shows 5 of the C1750.

Hi Bobby,
just a noob has a question:
If I use the Type B driver, and attach a dimmer and then i still put 4 cobs with dimming down the current below 2.8A,
the 4 cobs still will run? i assume then the brightness will decrease along the dim?

The voltage range is what you are concerned with. As long as the voltage isn't at the drivers minimum range when driven at max you should have no problem dropping the current when dimming. The cob datasheets have charts that will tell you the expected voltage at any particular current.

The Cree PCT shows 147.6Vf for 4 CXB3590 at 2800mA @ 50*C. Mean Well spec sheet shows overvoltage protection from 120 - 132V. Vf would still be 138 at half current.

another noob question:
If I dim down the current (lets say to 50% at 1.4mA), then the total consumed watt by 4 CXB3590 will decease down to approx 200w.
HLG-320H-C2800 allows Rated Power at 319.2w
so... can not run 4 COBs with dimming down below the max watt of the driver??

The voltage range is what's important, not watts. At 50C and 1400ma the voltage for each cob will be about 34.5. You need to check the HLG-320H-C datasheet as well. The 2800ma version provides 57-114 volts, so you would only be able to fit 3 CXB3590s on that driver. 4 will work with the 2100 version and the unit could be dimmed down to about 30 watts.
Hi Bobby, i saw some your posts on another forum where now you're banned. I'd really like to get from you an opinion about maen well hbg 100-48(A) driver VS hbg 60-1400. Both of them ar dimmable.
60-1400 is 1.4A, cheaper(cost half of the price)and ready to hanging but it hbg100 is 2A aloy and not plastic, is IP65 and from datasheet seem to have a good efficency run at about 60% ...so should be good to run at 1.4A..or may it be too warm VS hbg 60 run at full power (1.4A)?.
I don't need so much run it more than 1.4A but in the future maybe i will.
Hoping my english question is quite clear to undersand for you i'm waiting for an anser, from you or from other expert users.
