thats correct [email protected] = 209V
I would wonder. That would be some real high voltage honestly. YikesHi BOBBY_G,
do you also know if meanwell has plans to release HLG-600H-C series?
Greetz!
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.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.
the 'C' in the HLG-320H-C2800 means constant current. which means if you put 1 or 2 or 3 cobs on there (in series) and they will each run at 2.8A. 4 wont run at all as the voltage is too low
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 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.Hi Bobby,

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 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.so... can not run 4 COBs with dimming down below the max watt of the driver??
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.now thats some current!!!!
