RACK-IT! 500/51X -> to 19" rack and easy-to-test solution.

Where are front panels available? I have the partial kit from the online store but I need the front panel, thanks

So this would basically be a smart move if I had psu that runs at 24V (running two neves) and I want to run two additional 500 modules (ssl 9k) in the same box with the respective voltage, which then would be regulated down to 16V at igor's ps?

missing another 24V psu (and probably/maybe an additional +48V supply for phantom powered mics). Your 24V psu for your neves probably is a single rail psu. These 500/51x modules are powered by dual rails, IE +24V and -24V with a 0V reference voltage in between, that is 48V between these +/-rails, if it is a +/-24V supply. These rails can get regulated down to maybe +/-16V for the api500 format 15-pin cards by the RACK-IT.

hi guys,

I cant find the "18 PIN DUAL SIDE CONNECTOR PCB TERMINALS"on mouser.. If someone can help me, please ? Where to find this ?

thank you so much !

About to make the plunge into DIY 51x!

I should be able to hook up the Rackit power supply pads to a 7-pin Neutrik cable end, and connect that to a 51x PSU (specifically the one offered by Classic API: http://classicapi.com/catalog/product_info.php?cPath=176_178&products_id=359?

Mm yap. Rackit! 3

 

[canidoit]

What's new with rackit version 3?

 

[canidoit]

Mm yap. Rackit! 3

Ive just realised, this looks a bit like Radial Workhorse Powerstrip.
3 units in a 1 unit rack, is that correct??

When will this be out??

 

[Finlaywatt]

Is it still possible to get hold of these? Had a look on the store and couldn't see anything.

I second that motion!

I'll have these available in about 2 weeks. You can join the mailing list for notification here:

So what have people who've built this as a test tool used as the PSU?

Unfortunately my bench PSU is not bi-polar so I was considering getting a 48V switching PSU, putting it in a little box and then deriving the + / - 24V from that.  Seems like the cheapest and quickest option.

I've built 1 as a test supply and am in the process of building another (a more glorious one that will also run eurocard modules...)

I used a +/-24V card from dantimax for the first one, coupled with a cheapo hammond transformer. It works well enough to check a module is working fine, but the buzz from the transformer is a bit annoying..

The second one I'm using the nice little PSU card from diypartssupply and a £20 toroidal transformer from farnell...

 

[therecordingart]

Nevermind. Figured it out.

Is there somewhere a BOM and a guide for newbies?

There is surprisingly little documentation on this project. Has anyone else built it? Or is planning to build?

If so, I think it's best to attach the voltage regulators to the back panel before soldering the pins to the main board to ensure they are flush and don't stress the regulator solder pads when you tighten the screws, like this...




There may be no remaining interest in this project, but perhaps someone will come along years from now with questions and find this helpful.

PS: the existing holes did not line up so I drilled new ones. I also pushed the header pins (through the plastic guides) as far above the PCB as possible. Otherwise the capacitors on this board will bump the capacitors on the main board. More forthcoming...
