Cutter Electronics: Complete DIY COB kits

Growmau5 said:

Hello I'm growmau5. I contacted Mark over at www.cutter.com.au a few weeks ago to ask if he could package together some high quality components and offer us a 1-click solution to ordering the parts necessary to assembly the single most popular configuration for most growers here: Four of Cree's flagship 3590s @ 1400ma.

As a paid supporter and sponsor of RIU, Mark was happy to help us out. He mentioned that he had been thinking about doing this for some time and that he would fast track the only missing component from his site: the Heatsinks.

A lot of us have been using extruded bar heatsinks with great success for sometime now. And I am sure many of you will continue to enjoy the process of measuring, marking, drilling and tapping these type of heatsinks for your custom COB setup.

In my estimation, the heatsink machining and preparation process is the most intimidating part of a DIY COB build for most beginners, accounting for 60-70% of the time it takes to complete a build. To streamline and make this process easier for all of us, the guys at Cutter really went out above and beyond to source a Passive Anodized Pin heatsink for us :with a thermal resistance of 1.07 C/w. The increased heat emissivity of this design allows for smaller, lighter, more efficient thermal management at a comparable price.

OH, and did I mention they come pre-drilled and tapped for popular COB models including the Cree CXB3590!

If you are interested in learning more about this kit, follow this link directly to the kit page: http://www.cutter.com.au/proddetail.php?prod=cut2900

Here is what is included:
4 pcs Cree CXB3590, top bins only
4 pcs Ideal 50-2303CR CXB Holder
4 pcs Ideal 50-2300AN Adapter for the Ledil ANGELINA
4 pcs Ledil Angelina 90 Degree reflector
4 pcs Graphite Thermal pad(TIM) 1 side adhesive for simple assembly on the COB

1 pc LGSU-1400D, Dimmable driver allows the COBS to be run at just under 50 watts, the sweet spot of wall plate efficiency

1 pc 0-10V dimmer compatiable with the LGSU Driver

4 Passive Pin fin Coolers suitable for the 50 watt drive( based on eff% calculations), predrilled and tapped for the Ideal Holder and adapter( you will only need a screw driver not a drill press)

16 pcs M3 6mm screws for the Holders

16 pcs M3.5 12mm Screws for mounting to side rails


The kit is called the MAU5 : IV so that it is easy to find & so that newer hobbiests know they are ordering the same components I showcase on my YouTube Channel. I will also be offering installation support and instructional videos on wiring, assembly, & configurations.

Additionally, these heatsinks and Cutter Kits will be the foundation of a new series of videos that I am producing called: the
Community OpenSource DIY LED grow light

the goals of the series are :
-to cooperatively design and build a completely modular, adjustable, infinitely configurable system with standard components .
-affordability, global accessibility, high performance
-applicable to anyone from the closet grower to the warehouse grower.
-ease of assembly and use.
To complete the project I will be creating all of my files in a collaborative affordable software called: Autodesk Fusion 360 (free 30 day trial, $40/mo license). Publishing will go directly to my profile over at GRAB CAD, a free website were anyone can download files and send them to a local shop for fabrication.

I will also be assisting our community by reaching out to fabricators that will cut out parts and ship anywhere in the world. Places like Big Blue Saw can take one of these files , produce the part and ship to your doorstep for less than you might think. (more on that later).

In the meantime, I will be designing and fabricating prototypes that will hold the heatsink, allow for modularity, and allow flexibility for mounting other components like reds and UVs.

One note to USA buyers, the bold typeface prices on Cutter.com are in Australian dollars, US dollar conversions are listed below that.
The RIU discount code: CUTANDROLL will work for this kit!!!
Pre-orders are going on now (mid-march) for April 2016 availability.

Cheers

should be no problem, drivers will regulate the requirement as long as you have enough min/max voltage in the driver your good to go. Having more volts at the top end is no issue these remain unused

Thank you very much, Mark, for confirming that for me. I guess tgat means more diodes ordered from you soon cheers buddy

38 mm by 38mm. The chip in pic. Is anybody tried the Sun boards from The Phantom guy he's a respectable guy I don't think he's very polite if you ask me when you email him it's very hard to get him to understand what you're trying to ask him and if you ask him for any small deals without trying to get a large quantity ask not worth asking but he's a respectable stand up dealer from what I hear.
Big bich chip in pic good chip 50volt.
And Mark if you get this can you tell me do the clu48. 1216. Wood u pay 17$ech. Or 14 for 1212 lmk what to do i got 1212 cash suck i got a 3590 killer. 13000lums to19000lums

Hi Mark,

I am trying to run 3 x 250W ZPE drivers in parallel but when I plug them into the wall only 2 will fire. If I remove 1 driver the other 2 fire, if I add the 3rd, only 2 fire.

Each driver is connected to 2 x Vero 29C in series.

Do you know what the problem is? Is house wiring only capable of firing 2 of these drivers in parallel at one time?

Cheers.

Sounds to me like he has 3 drivers wired to 1 plug and can only get 2/3 to work at any given time.

klx said:

Exactly. I have had 2 drivers running in parallel for over a year but I want to add a third driver and 2 extra cobs to each fixture. But when I add the 3rd driver, only 2 drivers will fire. Its not the driver as I have swapped them out and still only 2 will fire. I am wondering if the inrush current on 3 drivers is too much but I am sure people run more than 3 all the time with no issues and each fixture would only be 600W at max??View attachment 4040002

what does the dc side of the circuit look like ?

Mullumbimby said:

How have you wired the ac side? Have you run three pairs of wires into a single plug?
I have similar drivers to yours and they each have a single mains plug and I just whack them into a conventional plug board.
This makes the ac side 'parallel' and I'm ok until I exceed the rated capacity of the plug board or my ac wall socket. That would need over 2.4Kw in my location - ie; over 10 amps at 240v. (this is the equivalent of more than 9 of your/our drivers).
When people in this business refer to 'parallel' wiring for LEDs, they are almost always describing the DC side.

Yeah thats whats weird cos even when I put a plug on each diver and plug them into a powerboard, only 2 of them will light up.

When I say they are wired in parallel, I mean they are all wired to one plug. All the positives go to the positive of the plug, negative to negative etc.
