Alphapix vs Falcon?

Recommended Posts

I will be making a purchase this week, deciding on the controller for our mega tree. I know the Falcon has a good reputation. We currently run an Alphapix for our ribbon tree and have had no issues. Either controller would be customized for additional outputs.

Falcon V3 with two 350 watt Meanwell supplies and 32 channel outputs. I could only run the tree at 30%, per Brian at HLE Cost is $650. Additional power options could be a few hundred more.

Two Alphapix16 units, two 350 Watt Meanwell supplies. Per David at HC, this could be run at up to 70%.

I am not concerned about the price difference as much as I am about the ability to only run the display at 30%.

Well I run a couple falcons one is using  24 outputs with 2 30 amp 350 watt power supplies 100 2811 pixels each output at 100 % I have no problems  why did HLE say  only 30% I also think the Falcon is one of the easiest E1-31 controllers to setup  just my opinion .

How many strings and how many pixels per string?

I have run a few different controllers including the alphapix.

And the Falcon is the best controller you can get for the money today.

In fact I was so impressed with them I bought four controllers last year to replace everything that I had and I have one of the new f48 on order. 

3 of My f-16v3 are set up with 4 400w power supplies so I have a hundred watts per output.

A few hundred for additional power options. I can buy a MW PS-750-12 for $30. I run 24X50 channels at 100% easily with the 750. Is this a 32 X 100 tree? Mine are run off LOR pixie16's and a pixie16/pixie8 combo for my 24x50 matrix

Sorry, I should have noted that. Looking at 24 strings x 120 pixels per strand. 2880 total.

F16v3 and expansion board would probably be best/cheapest bet with one psu per bank with 4 psus total if you limit intensity.  Two 350w psus's isn't going to run that tree.  DMoore @ Holiday Coro needs to punch the numbers again...  Call DPitts not DMoore.

That is very similar to what I am doing with my pixel tree this year.  Mine will be 24 x 100 plus 270 pixels in the star on top. I have always used SanDevices controllers for my pixels, so I will have two E682 controllers for the tree and star.

I would not listen to anything Brian, he obviously has no idea what he is talking about.. There is a reason everyone prefers the Falcon over the all others. The Falcon F16 V3 is $200, expansion board is $50, 2 PSU's $70, that is only $320.

If you need the larger 750 PSUS let me know at under $30 each you cannot beat that price. Meanwell PS-750-12. Cant post link here but can send it via pm

This doesn't make sense - the controllers take very little power and the only thing you are changing in this scenario is the controller.   It doesn't quite work like this, but that would sort of imply that the Falcon uses (or wastes) 280 watts more than the Alpha (40% diff * 700w).  There is no way that is right.

Good impartial compare of options is here - http://nutcracker123.com/nutcracker/rgb_controllers/

Disclaimer alert - I run a F4v3 (with expansion) and just picked up a F16v3

Didn't find any references to a MW ps-750-12?      Did see SP-750-12 and RSP-750-12 but they are in the $200 range. 

I was running several Sandevices E6804 (4 outputs) and upgrade the past yearr to several F16V3's...I'm totally impress in what Falcon is doing.   Wth their rep, never even consider any other 16 channel controllers.     Doesn't HC have an additional charge for "support'.

 

Just learned of their "differential board and receiver" that lets you place a reciever (4 outputs), 250ft from the F16....I placed an order right on the sport for the differential gear.     It's this kind of technology that IMO, makes Falcon the industry leader in pixel controllers.

That's  a good point...at the end of the day, both of these setups have the same power supply. I think I could run the mega tree in the 50% range...but 30% wouldn't give me enough flexibility.

 

So for the power and pixel gurus...can anyone give us concrete info on 700w of power running 2880 pixels? All white isn't necessary.

That MIGHT get you by.  The rough rule of thumb I tend to use is 1,000 pixels for each 350W power supply.  That will get you full white but not much extra.  Depends on the pixels too - A LOT.

The number of power supplies you will need depends on 1) wattage of each pixel 2) total number of pixels - the attached calculator shows several examples, and also allows you to enter your own.
(make sure you hover your mouse of the row header to see the explanation comments.)

Wattage of pixels is obtained from the vendor's website, pixels can range from .3 W to .8 W each, which is a big difference in total watts when using 1,000s of pixels

Numbers of power supplies required is based on running the power supply at 85% of it's maximum rated output (this is a generalised recommended max) for all white pixels with controller at 100% brightness.

Obviously you'll also need an amount of power for the controller itself, though most 16 ch rgb controllers don't use that much power (yet to find power usage ratings for rgb controllers).

Obviously if you run your controllers at reduced brightness (I run mine at 40-50% and it's still quite bright to look at) then you could get away with fewer power supplies in some instances. Word of warning - relying on reduced brightness in the controller to overcome power draw from the power supply could have catastrophic consequences, do so at own risk. 

 

In the scheme of things the cost of power supplies is not that much, if you are going to power inject (which you'll need to for 24 strings of 120 pixels) then you may as well be conservative. Design for all white pixels (ie max wattage per pixel) with controller at 100% brightness and max of 85% power draw from power supply; and you shouldn't have any issues.

what he said, I have used both and the Falcon by far is the better of the two.  And you don't need a 1400 watt power supply! :)
