Higher wattage Transformers 500W/750W/1000W
« on: April 22, 2018, 04:12:27 PM »
I see everyone always using 350W transformers for there pixels, is there a reason for this? With the ability to get 500W/750W even 1000W, why arent we using these? Is there an adverse effect that I am not thinking of?


Seems like not a bad idea to reduce the amount of needed transformers in an enclosure.


Is anyone using higher wattage transformers?


Thanks.

I assume/hope that you mean power supplies and not transformers.
The biggest issue going much bigger than 350/360/400W is that the cost per Watt tends to go up a fair bit. There's no actual power issue distributing the higher wattages.
The other issue is that for those with 110/120V power you start getting way up there with the input current. A fully loaded 1000W power supply will pull about 10A at 110V. It's also quite common that the 750 and 1000W supplies will only run off 240V.

I think an even bigger reason is that most of us began in this hobby using the CG-1500 boxes and the 350 watt power supplies fit in those boxes pretty well.  It is only recently that folks have begun to use larger enclosures to any extent.  The larger enclosures allow the use of much bigger supplies.  If I had it to do over, I would be using 750 watt supplies throughout.   8)

lighting guru, I think you are not reading all the posts as there have been lots of posts of folks using larger power supplies.  But I think it has only been in the last two years that the trend has started.  I suspect that may be somewhat influenced by another trend and that is to centralized control from distributed control.  That is a pendulum that seems to swing back and forth in the computing business and now in the lighting arena.  I for one light to minimize having data cables laying all over my yard and use smaller controllers that are located by the props.  In that situation there is no need for a large power supply.  YMMV  They all work, it is nice to have options and choices.

I use the 350 W power supplies for the same reason as Jim states. I can have the power closer to where I need it. It's all a personal choice. There is no right or wrong way to do it, do what works best for you.

I'm in favor of several smaller supplys spread out through the show. I've had a few go bad in the ten years I've been doing shows one small power supply goes bad one small section is out one big power supply goes bad your dark  just my opion.

I agree with what others have stated about trying to get your power as close as possible as you can to the props they power. That being said, there are times when you need a lot of power in one location, and I have been seeing a lot of controller enclosure builds with 4-350W power supplies. If you have a need to put that much power in one enclosure, then there is nothing wrong with using fewer large power supplies vs more small ones. In fact, the one advantage I can think of is that if you have one larger power supply as opposed to two smaller ones, you don't have to worry about keeping the positive leads separated.

Of course, regardless of which way you go, you should always keep spares on hand.

I'm in the minority I can see... I love the larger power supplies myself.  I have 4 of the Meanwell RSP3000-12 in my display.  Three of them running in parallel for 600a @ 12v. If one fails I can limp by with two and I keep a spare on hand.  I was tired of the cluster of CG1500's and 320w psus.  Pros and cons to large power supplies.

where did you pick up that beast Dan?


I got a couple 500watt Cosel off ebay a couple years ago, wish had bought 10!


some folks use 1000watt server supplies they get real cheap used.
