Topic: Bladecenter H 2880W Breakout Boards. Selling from stock, limited time discount - page 10. (Read 34325 times)

Very nice looking! I am interested in one, possibly 2, of these boards. My setup is long overdue for a cleanup, and these will provide just the reason. Looking forward to updates and solid pricing.

Hi, I assume you will use it for RC chargers or something similar, since you want to raise the voltage.
Unfortunately, I won't have any spare 12v connector until my order for the 140 ones will be delivered, end of january.
The 220v one is easier to find, and not that expensive.
I even have some already wired to an EU plug from my first tests.

As for internal schematics, this PSU is quite undocumented. "external" pinout is available, but nothing else.
I'm not sure if they explained how to, but I've read somewhere that people were able to raise the voltage, I'll have a look if I can retrieve the data.

If you are interested in the 220v connector wired to EU plug (or with bare wire for you to put the plug you want), just send me a private message.

Hi!

in a few days my  Astec AA23920L should arrive ... as I want to connect a BIG cable directly to the PSU, I am asking if its possible only to buy the Connector for 230V and the 12V ?

Do you have any internal information about that PSU such as pinouts ? Would be great if this PSU can deliver higher voltages (such as 14V) ... do you have any schematics?

I really appreciate your answer!

Best regards,
Martin

PM'ed back, finally.

First post updated with the "reserved" quantities.

Since the first steps in pricing are reached, worst case will be 60$ a board + shipping.

Only the first batch will need the 6 weeks delay since the connectors will then be ordered in advance. The other ones will be either in stock or short delay
I have a first batch of connector already ordered, but once I'll reach 75 reserved boards from this first batch, I'll order a second batch of 140 connectors.
And you are right, the DPS 2000 does have a few bad points, that's why I looked at something else with some nice power.

What I was really saying is this might be something you'll have to put down for in advance, and sell as they're in stock or a few weeks out. If you can cover those pins then its a significant USP over the DPS2000-BB which has exposed stuff everywhere without a case, and has downward facing pins which get very close to whatever shelving you use. Those that use metallic shelving or even treated wood have to be careful and usually sit it on something.

Unfortunately, many FCI connectors aren't stocked anywhere and seems to be manufactured on request.
That's why I need some time to get them.

Your request on the pins cover is legit, I'll have a look at something easy to do.
Worst case will be to cover them with some non conductive rubber.

you got reply.

Oh interesting design. I think as a few others have said, it will be hard to justify a 6 week lead time as people either need PSUs now or they don't need PSUs. Will also have to find a reliable and bountiful source of the PSUs themselves.

Ps, can you create a tiny plastic cover for the interface pins that are visible on the front side? Then that front side has no touchable live surfaces.

I would be interested for sure but 6 weeks is too far out.   Sending PM

Exactly, you were faster than me.

here is a pic of the 3 pins proprietary connector

That PSU does not have the conventional C## input plug, only a proprietary IBM connector.

I'm not sure I understand what the C20 is doing there?

Really nice man

Edit, the board design changed from 16 to 22 PCI-E connectors to allow it to maxmize the use with ant S5 units. 5.5 ant S5 will draw 5.5*500w=2750w from the PSU

The idea behind this breakout board is to cut down the Power Distribution Units cost for larger farms with a high efficiency PSU that's 1.5 to 2 times more powerful than the often used Common Slot and DPS 2000 BB PSUs.
Another advantage of the Bladecenter H PSU is that it does already have the fans, unlike the DPS 2000 that could be time consuming to setup for large deployment.

Not to forget, the Bladecenter H PSUs are 80+ Platinum certified, 94% efficiency.

After making a small batch as a proof of concept, I'm wondering if there would be enough interest in these to make a bigger batch.
The main connector does have a 140pcs MOQ with 6 weeks delay.

Technical data:
IEC C20 input Plug
22x 6 pins PCI-E connectors rated 9A per pin (27A max per 6 pins cable) to allow up to 5.5 ant S5 on each PSU
PCB with 4 layers of 2 Oz copper.

Pricing excluding shipping for each board will be as follow:
1-25 boards total ordered -> 70$
26-50 boards total ordered -> 65$
51-100 boards total ordered -> 60$
over 100 boards total ordered -> 55$

Since there was a little more interest that I expected, this first batch with flat price will close at 200 Pcs or on the 11th january 2015 whatever comes first.
Orders made past this limit will only be processed the first week of february, and the flat rate pricing of 55$ a board won't apply anymore. You will pay a price based on the quantity you will individually order as I'm already offering on the other boards.

Pricing for 16 AWG cables with plug at both ends will be as follow:
My home made cables are using 1.5mm² copper wires.
according to tables, 16AWG is 1.31mm², 15AWG is 1.65mm²

Price for those will be
2.5$ for 24"/60cm
4.0$ for 36"/90cm

I can also source cables with 16AWG aluminium wires, the price should be 0.6-0.8$ cheaper than the copper ones.

For those of you who'd want to make the cables or add a connector to existing cables, I'm also able to provide the crimp pins and 6 pins connectors at a fair price:
0.20$ the 6 pins connector, and 0.04$ the crimp pin

Boards for small orders will be delivered as one batch in the US and stocked by a reseller to be dispatched to end users at lower shipping cost.

If a few boards are needed before I get the connectors from the manufacturer, I can have a few as I did for the first prototypes, but individual price for the boards will be close to 80$.


Here are some pics of the actual board and of the first order before it's shipped.

If you are interested in this product, you can either PM me or post here with Qty you'd need and country to ship.
I'll update a list here, and if i can have enough interest in them, I'll ask for a deposit of 10$ per board in the first weeks of january for a delivery expected by the end of january.
