I need to power my BFD and M-one motor from a Sony DSR 450 that uses IDX V-lock batteries while the camera is NOT on my sled.

I have the Anton Bauer P-Tap but nothing for the V-locks. Not even sure there is such an option or solution? Already sent an email to Jim.

Needed Saturday thru Tuesday in LA. Rental or loan would be very much appreciated.

Cell: seven-0-two 810-5707
email: robert*at*lasvegassteadicam*dot*com

I'm open to other powering options as well if you have any ideas.

Thanks!!!

I'm reasonably sure that camera, and many other ENG style cameras have a 4pin Hirose in the rear that delivers 12V power out. Getting a cable that works with that jack would be a very universal solution.

Be wary of that 4 pin Hirose. Some of the camera's aren't designed to supply the amperage out of those connectors. I think on the Varicam it's only 400mah. Fine for 2 wireless packs, but you may blow the breaker if you try to power the BFD.

Robert,

One solution is to use 2 adapter plates. Get and IDX to anton bauer plate, and an anton bauer back to V-Mount. The Anton Plate should have the P-tap you need. Not ideal, but it should work.

Our IDX plate does have a p-tap on it. But that may vary depending on type. I guess they may not all have it.

Robert,
Steer well clear of the 12 pin Hirose on the rear of video / HD cameras. 9 times out of 10 if you power anything off it other than a radio mic receiver, you'll blow the fuse. There is a Sony upgrade for this which improves the rating of the hirose, but generally it's impossible to tell if it's safe to use for our needs.

You will find that on the DSR-450 there is an identical Anton/Bauer style D-Tap connector on the camera handle (virtually all one piece video cameras have this feature, designed to power a camera onboard top light). This D-Tap is identical to the D-Tap you'd find on an Anton/Bauer battery plate, and is suitable for us to use for video TX's. Use this port with your existing cable and you'll be fine. You can even make up a D-Tap splitter cable if you're feeling brave, to 2 x 4 pin XLRs - then you can power 2 accessories off the one port, should you so desire.

Hope this helps, good luck.
Jason

Hey Jason, whats up

I tryd that ones, didnt work. Reciever and 2 motors drawn to much, so it goes bollock. Those p - tap ports are for 20 w lights. But it wont even start up my Kino ringlight. ( thats a 20 watt light ) Guess the dimmer needs more too.

In the worst case you could ask Jim to make you a cvable from your bfd to xlr. I have that in my kit in case i need to power the ff when not on my sled, but on my crane. Then you could use a battery belt, or charger ( most of them also work as supplier ) Or something else that takes xlr.

Hope that helps

Hey Job, hope you're doing OK.
I'm pretty certain the one on the DSR-450 is rated at 50W; the other week I powered Teletest transmitter and a BFD / M-One off this port OK, it was fine. That said, I've never tried running 2 motors off it, always focus only.

Good point though, I try and make sure that every bit of kit I have has a 4 pin XLR cable, that way you know you can power it from anything. It's also good practice to have a small case in the van with power and video cables / connectors / adapters from anything, to anything - that way you can never get caught out!

Thanks to everyone for the calls, emails, offers and posts. The P-Tap connector on the camera ultimately powered the BFD and M-one motor just fine; though I never sorted out what its power rating is.

Again, thanks for your help.
