I got something like this, and it seems to work well (I don't have my BMCC yet, but I have used it on an EX1, an Arrow HD transmitter, Z7U, Z5U and my alphatronics EVF. Mine doesn't have the HDMI DA, or the switch, but it seems to work pretty well. The only thing I need to add is the switch, because the LDO voltage regulators inside will pull a very small current even without anything attached.
Also note that dionics get confused with having no load but a small trickle current. so at least for dionics their fuel gauge will blink with a solid black line. In the coming days I am going to test it with an interactive hytron, and I am hoping to get better results.
Also note that the LDOs are limited in the current they can source. I haven't done a full part lookup, but most LDOs in the TO-220 form factor limit out at about 1.5A (18-21watts). This limit does not apply to the 15v out, or the D-tap out, which is unregulated. I'll have a better write up on its capabilities once I put the Alphatronics, livelens, phantom power, and BMCC on power all at once. Most LDO's fail closed, so shouldn't pose an issue if you were to short them out. There is no current limit circuit on the LDOs, so if you do have a short, the LDOs will source as much current as their output transistors can, until the point that they fail.
This might be an issue with any distribution pack you might find on the market. Unless you do a full circuit analysis there is no way to tell-nobody puts these things on their data sheets.
either way, I spent 120 for mine, which would be a deal for an AB plate, let alone something that has 15mm rod adapters and LDO regulated distribution.
