LED Meanwell Dimmable Driver Questions

[rvales]

Reaching to you LED experts. Who sells Meanwell drivers the cheapest and which Meanwell dimmable drivers do you recommend. I will run them from my Neptune Apex, so I need 3 independent drivers to run 12 LEDs each of the following (Below):

Epileds Green LED 3W
Wavelength: 520-525nm
Forward voltage: 3.5V @700mA
Efficiency: 30 lm/W
Max. current: 700mA

Epileds UltraViolet(UV) LED 3W
Max. wavelength: 398nm
Forward voltage: 3.8V @700mA, 3.6V @500mA, 3.44V @350mA
Radiant flux: min. 75mW max. 180mW
Max. current: 700mA

Epileds Red LED 3W
Peak Wavelength: 660nm
Forward voltage: 2.5V @700mA, 2.33V @500mA, 2.24 @350mA
Max. current: 700mA

Can anyone please tell me how to calculate the correct voltage and wattage I need and do I connect them parallel in sets of 6, so I have 2 sets of 6 on each driver?

Run them in series...Just add voltage at the current you want to drive them at.

3.6V @500mA,

So you need a 500mA driver outputting 3.6x 2 V = 43.2V minimum..

One of the arguably simpler choices is a separate power suppy, LDD-H drivers and a converter board between the 0-10V Apex and the 5V PWM dimming of the LDD.
A 48V switching power supply @2A or more would power the 3 drivers
Amps add in parallel, voltage in series..

As a side question.. why so much green??
A RGB =W idea??

As only ONE of numerous examples:

Set DIP switch to 500mA and good to go..

I like the Meanwell LPF series if you want an all in one ac->dc/constant current output.

It allows the 0-10V as well as PWM and potentiometer (3 in 1 dimming)
Based on Oreos math of 500mA @43.2V min the LPF-25D-48 is perfect..
Just above $20/ea

I currently have a fixture I built a few years ago it consist of 90 whites and 90 blues with 8 Meanwell eln-60-48 drivers. it also has 5 heat sinks. I plan to use the UV's, Greens and reds to supplement the colors. with 4 heat sinks in between the 5 existing with 9 LEDs on each.

LPF-25D-48 sounds like the route I will take. Do you have a place with good pricing?

Just google.. They are all pretty close to the same price all over the place..
$23-25 across the board..
onlinecomponents, mouser,etc...

Thank you all for your replies. It was very helpful. I plan on finishing the build within a month or 2. I will post some pics when I do.

I think you will be happy with the LPF series.. I've been out of the DIY game for a while now and there "could" be slightly better ones but IMO its all one needs..
They are better than the ELN series that people were using for a while due to the 3-1 dimming vs just pwm or just analog,etc..
The LDD's are nice but for only a few strings I don't see the point of having to buy a power supply, circuit board for the LDD (or discrete wire ones), etc.. The LPF is all in one.. Just plug into wall and wire to LEDs and attach dimming circuit and good to go..

Good luck.. have fun..

Thank you, I hope to have them up and running in the fixture soon.
