That was my thought. Never read of anyone running the "B" model that way. With dim wires open it could only output 18volts or up to it's max, not sure if it would auto adjust voltage higher or lower though by itself, like you can on the "A" models (up to 38.5v) with the on board pot if needed, or dial it down to run the LDD's more efficiently for smaller strings.

I'm very curious how the "B" version will behave with a driver attached instead of an LED.

The -B model is the same as the others in the series if no dimming signal is present.

1) controler PWN 0-10v GHL Profilux
2) Meanwell HGL 240-36B (Dimmable)
3) Chip China
a ) 5 Chanel
b) 36V Each chanel
c) 700 -1200 mA echo chanel
4) Chanel 1 in Row of 10 Chip
Chanel 2 in Row of 10 Chip
....... Until 5

I hope this is the correct way that you can tell me what I have to change to
Be able to Dimm down (at least to 2%) not like I have it now until 15%

Ok, for that, you'll need to order fifty (yes, 50x) Meanwell LDD-500H or 600H. Those Chinese multichips do not like being pushed harder than 700mA, and some don't do well even at that current due to poor thermal performance.

Onlinecomponents.com has exactly 50 in stock right now, $3.38 each. http://www.onlinecomponents.com/mean...f=OctopartFeed

You will also need boards to mount them on. LED groupbuy has 5up boards that are preassembled. You will need ten of those. Do a google search to get to them, this site will break the link to it.

You will also need new power supplies. The 36v ones you have now will not work due to the LDD needing more than 36v input to be able to output 36v. I recommend sticking with HLG. You will need five HLG-320H-48, power two LDD boards (and therefore two total chips) per power supply.

Each channel of the chips are 10 diodes(possibly 2 parallel rows of 10).. Pretty sure he can get away w/ 33V
(3.3V each diode) w/ only a minimal loss of output..esp If you drop the meanwells to 500mA

Though "spitting" a 500mA in 2 (2 parallel rows) is only 250mA per row...
I can't quite tell from the photo but it looks like 20 1W diodes /channel 2 rows of 10..

you forgot O2's "special sauce" converter boards to turn 1-10V DC to 0-5V PWM...

As long as the current demand does not go to the "constant current" region it will output full rated voltage. Hooked to 2 LDD's it will never achieve full current.

oreo57 · 04/06/2015, 11:04 AM

Or 5 for that matter.. As long as they total <6A

Didn't notice that they had double the amount of LEDs as typical - that is why it is able to use 1.2A per 'channel', as it is splitting it into two 600mA strings. Even still, the board they're mounted to I doubt can dissipate ~216w per multichip. Running on a 700mA LDD will give each 350mA, total chip wattage will be around 115w, which is still quite a bit to deal with unless the PCB is copper.

Actually closer to 6.4A total - 95% of maximum current output is where it is designed to switch over.

500ma drivers will keep the Watts below 100.. Which I would guess is about all they can "truly" handle..
Substituting some bigger mA's to a channel or 2 "down the road" of course is an option.
Don't think the O/p was expecting this $300 plus for a rebuild to "do it right"..

oreo57 · 04/06/2015, 03:52 PM

O/P?????................. gone.

Sascha1966 · 04/07/2015, 06:00 PM

O/P Is here! Needed to work to Get the 300$ Plus, to do it ight. All sunds really great! But I do not understand one word. Too much input for someone who has absolutely no electronic backround. But i will try to follow your instructions. Thanks for all input !

If you build this units already solving this problem, would it not possible to build one for me also ?
