DIY Radeon clone?

[MikeyA]

My tank is 48x40x22 and I'm running 2 rows of 3 pucks each. Also running 12x3w rb and 6x3w mint. Running a total of 7 channels on each row.

With 6 t5 in between each led row.

The coverage, customizable color and par are unreal!

 

[MikeyA]

My pucks are from kiwilighting. I had them change several channels for me.
Chan1 5xrb 1500ma (80%)
Chan2 3xnw, 2xww 1000ma (50%)
Chan3 5xuv-violet (395-430nm) 600ma (90%)
Chan4 2xcyan, 2xnw, 1 430nm 600ma (60%)
Chan5 5x 480 blue 1000ma (70%)
Chan6 12x3w rb 1000ma (80%)
Chan7 6x mint 700ma (60%)
Chan8 I'm debating

Hi there. Just wanted to know how many pucks would I need for a 1.2m x 0.45m x 0.45m?

@MikeyA just a quick question. Or if anyone can assist. Would 3 or 4 pucks be able to run on 5 LDD 1000H meanwell drivers? So basically connecting the 3 or 4 pucks, depending how many I get, to each other in series. Then wire the channels of the different pucks to each other. Eg. Puck 1 channel One to Puck 2 Channel Two then to the Driver for channel 2?
Would these drivers be able to run a 3 or 4 puck series?
Thanks

@ZaheerR, I think you may be a little confused how the ldd works. So you can run 3 or 4 pucks in series depending on your power supply. The ldd are strictly for channel intensity control (which in turn can control color). So if your pucks have 5 channels each puck, then you'll need 5 ldd's and a 5up channel board to mount the ldd's onto. Also you'll need a controller with pwm capabilities to control the power input to each channel.

 

[MikeyA]

The ldd H meanwell drivers use pwm input to control how much voltage each led gets. The ldd's get power from the power supply. Look at the ldd's as a valve (for lack of better term). The power supply provides power to the ldd and the controller tells the ldd how much power to push to each channel on the pucks

 

[ZaheerR]

Thanks for the help @MikeyA . Appreciate it. What power supply would you suggest for a 3 or 4 puck system ? As well as im thinking of controlling the lights with a reef pi, would that be ok ?

There are 3 things you need to understand
1) Diode voltage adds in series
2) ldd drivers are simple voltage regulators for the most part and lowers the voltage to keep the current draw at a particular setpoint. They can't raise voltage.
3) They also can't output the same maximum voltage of the power supply.
There are losses. Usually around 3 volts
A 48v power supply only had 45v available to use.

Sooo pucks or strings if all are wired in series and you have a 48v power so you only have 43 volt
If your diodes have a voltage spec of say 3.4 volts so you can run 12 diodes in series .

 

[MikeyA]

Yes one ldd can power a channel on 3-4 pucks. For power supply, depends on how many leds are on each channel and how many pucks you are going to use.

https://www.ebay.com/itm/373318841933I'll be using these pucks. So let's say I go with 4 pucks, which one would you suggest I go with?
Thanks

 

[MikeyA]

Well, I'm uncertain at what ma you'll be driving the pucks at and without truly sitting down and doing the math, just a rough estimate of each Chan at 1000ma (which I know every channel can't handle 1000ma) at 4 pucks. I'd run a meanwell hlg 320h-54a. I also believe in leaving room/ power for expansion.

ASSUMING each channel is 12v each and you run 4 pucks in series you have 48V need per channel..
NOTE I now see 14-15V V(f) on the violet/uv channel
SOO 15 x 4 = 60 Volts THAT is an issue..
AS AN EXERCISE I WILL ASSUME 12V each FOR..THE ..MOMENT.

And you will use 1 LDD-H (not LDD-L) per channel.
Technically you need 51V per channel (remember the 3v loss w/ the LDD)

A 56V dc power supply would ASSURE you are running all channels correctly.
As to wattage that is even a bit harder to estimate BUT again assuming 48V (4x12) per channel and 1000mA ldd per channel:
48 x 1 = 48W x 5 = 240 Watts.
So a 56V 240Watt power supply would be fine..

NOW back to reality a bit and WHAT to do w/ the 14-15V channel.
2 Choices split the array into 2 series/parallel sets which means you need 24V ps and a 2000mA driver per set because current is SPLIT in 2 due to the 2 parallel branches.

REALISTICALLY you will just double the number of ldd so you have 2 per color 1 for 2 pucks and only need a power supply of 28V...
But instead of 5 drivers you need 10.
And again you need to add voltage due to the losses w/ the LDD.
So going w/ the nearest and easiest choice a 36V power supply @240 Watts. Well more due to the violets.
24x 1 x 8 + 28 x 1 x 2 = 248Watts
Add 10% for good measure ..

PART #: LRS-350-36

https://www.ledsupply.com/power-supplies/mean-well-lrs-enclosed
Bottom line 36v 350Watt power supply (overkill but safe)
10 LDD-1000h (or ldd-HW if you want to work with wires) ..1 per every 2
series pucks..

I suspect this is the most common LDD based arrangement w/ 4 pucks
One can run 3 in series w/ a 48V power supply but leaves an odd 1 puck

You can add big AC/DC drivers to run 4 in series w/ usually 10V dimming.
PART of your decision is HOW (if you do) you want to control them.

I'd run a meanwell hlg 320h-54a. I also believe in leaving room/ power for expansion.

A single one can drive all channels (all channels in parallel and 4 boards in series) MAYBE but:

1) USE the "AB" one to adj. both voltage and amps and still have dimming.
2)Dimming will be global (no channel control)
3) running 5 parallel strings is problematic.

hlg 320h-54AB

Now to the "maybe" part.
UV/violet is listed at 14-15V ..the above driver can be tweaked to 58V
14 x 4 = 56V.... 15 x 4 is 60V

NOT that the listed voltages are realistic and they don't list the current that voltage occurs..

2.97- 5.95A adj range
5.95/5 =1190mA per channel
2.97/5 = 594mA per channel

Hi, what power supply to 2 puck xr30 3535?

3535 is a diode size.

 

[theatrus]

Also a common 3.5mm square LED.

But you're going to need to provide more information on what you have and what you're trying to do.

Are the Shines still available ?

I do have blanks and some LEDs, upon request :)

Do you mind shooting me a PM with diode choices,pricing and dimenions of the board pretty pretty please lol ?

I did buy in aliexpress two this punk. What need buy to this led configuration with app in cell?
See here tell very much... LDD, but no understand .
