Has Anyone attempted to connect Meanwell ELN-60-48P drivers to an LED Control4 ?

[Blahenazo]

how many drivers /leds do you use ?

[TheManicFishkeeper]

60 LEDs driven by 5 drivers combined with 16 T5's driven by 8 ballasts

[TheManicFishkeeper]

There are 2 strings of 12 Cree XP-G series White LED's driven by Meanwell ELN-60-48P's to provide the white lights and Lightning flashes.

The Blue LED's are 2 strings of 12 Cree XP-E series Royal Blues driven by Meanwell ELN-60-48D's, and a 50/50 string of 6 XP-G (White) and 6 XP-E (Blue) LED's driven by a 3rd Meanwell ELN-60-48D.

The White LED's are driven at 1100mA, the Blue LED's are driven at 900mA and the 50/50 string is driven at 750mA.

Hi, This is awesome.
I am looking to do a similar thing. Would you mind sharing the details
A schematic would be great and also maybe a mud map of how you hooked everything up.

I have a 6ft x 2.5ft.
My first project is to create some moon lights dimmable.

Project 2:
I also have 3x 150watt cree light units that I want to retrofit to controll via the profilux. They are just basic 50/50 blue/white that are switched on/off

Kind Regards,
Hem

assuming you have 3 x 150 watt crees ( @ 3 watt a piece ) you have
3 times 50 leds => 12 leds per driver ? that 15's meanwell drivers you will need

with this amount I would take a save bet and suggest to go for a Active led control otherwise you will need to much ports to steer all the drivers.

Thanks for your reply.
Firstly, should I start a new thread, I don't want to hijack this one if not appropriate

You are correct each unit has 50 x3watt LEDs (25 white/25 blue).
I am not sure what you mean by 12 leds per driver ? Would i not just need 1 driver for the white and 1 driver for the blue @ 75 watts per driver.
So for the total of 3 units I would need 6 drivers ? Or am I missing something.
Please bear with me I am just starting out with this and have a LOT (everything) to learn

[Blahenazo]

assuming you used the same drivers (like Meanwell ELN-60-48D) as the thread starter you can only drive 12 a 13 leds of the 3 watt crees per driver

if you use another driver it can be a total differenct story offcourse

[TheManicFishkeeper]

LED's are current devices, the "wattage" rating that manufacturers give is only an approximation. Meanwell Drivers power the LED strings based on teh forward voltage of the string, and set current rating (the current is what sets the LED's "brightnes").

Cree XP led's run at about 3.2-3.5 volts each, so a string of 12 LED's will run at about 38.4-42 Volts. A Meanwell ELN-60-48D (or P) driver can power between 24-48 Volts so your maximum number of LED's per string is around 12-13 (approximately).

Once you have your voltage calculations for your driver you then have to dial in your mA on your string to make sure the LED's are running within their rated spec's. For a Cree XP-E Series LED the MAXIMUM mA you should run them at is 1000mA, however a more conservative 750mA is better (they burn almost as bright, but run cooler).

You should definately do some additional research about your LED's before beginning your project. Using the standard meanwell ELN-60-48D (or P series) drivers you will need a minimum of 12 Drivers (You can run up to 13 LED's per driver).

if the 10V come from an external PSU then the above picture is right (in this case you have + and - from the PSU)

if the 10V come from the Meanwell driver you don`t need the connection to -

For the same meanwell driver (ELN-60-48P).

is it possible to use an external PSU with 12V? or different?
is it possible to use same 47k resistor pollup?

[TheManicFishkeeper]

Must be 10V, 12V would put too much voltage through the PWM circuit.
