Anybody using Anton Bauer?

ANYBODY USING ANTON BAUER BATTERIES...

I was able to pick up 3 or 4 AB Trimpac battery packs and am currently looking into getting the chargwer and gold mounts to wire my sled for 12v/24v and 7.2v for my Canon XL1. I have a Lilliput 7" LCD monitor that runs 12vDC nominal, and an operational range of 11-13 volts.

Just wondering if anyone else has used Anton Bauer batteries in their sleds, and how they set it up, what problems they ran into, and if you were successful...how you wired it up and mounted everything. Also... if anybody knows the answer to this.... is a 14.4v Anton Bauer Trimpac battery suitable for 12v nominal equipment?

The 14.4v system *should* work, but I'd get a 12v Regulator just to be sure. They're available pretty cheap at your local Radioshack.

[David West]

maybe one of the electronic gurus in the groups could help with a little schematic with a regulator and a cap ....

wade,
just for fun put a volt meter on the "in the wall" power adapter for your monitor if you have one....

Hi:
14.4 v AB are ok for most broadcast equipment (usually 11-17V) but is over the range for your monitor if labeled 11-13V (the AB are close to 16-17V fully charged).
You shoul get a 12V regulator for the monitor and a 7.2V for your XL-1.

There are dedicated integrated circuits that regulate to a a certain voltage with minimal external components. (I think something like LM7812 for 12v, 7805 for 5V,  7807 for 7V etc.)
I´ll do a little research and post the results.

Best regards

Here is a PDF of a schematic using the LM317 voltage regulator. It is what I use on my sled:

Voltage Regulator Schematic

I use this to clean up the power from my drill batteries to to my monitor. The nice thing is that it is tuneable. By using the potentiometer, you can vary the output voltage.

hi wade,
i'm using anton batteries and when it is full charged, the voltage is normally at about 15+ volt. i don't have any problem with the lcd monitor which i have on the rig.

[Wade Francom]

Is your monitor 12v nominal? What is the range of your monitor (10v-15v?)? What is the brand you are using?

Ed, what charger are you using to charge your anton bauer?

[Ed Liew]

here is the spec from the user guide:

brand - JEC
model - JM-256
power input/consumption - DC12V+/-10%, <700mW

i'm using the anton titan charger. when the battery is full charged, the info in my camera view finder show 15.6V to 16V, depending on the life spend of each battery.

Wade, I use AB Hytron 50's on my rig and also have a 120 if I need to go all day. I use the T2 charger in the studio but have a Titan Twin that I keep in one of the grip boxes when I'm away for a few days.

I highly recommend the AB QR-XL-1C mount for the XL cameras. They have a hard wired 7.2v output with the proprietary Canon power plate connected to it and a 14.4v power tap on the top. I had questions about the 7.2v connection as my rig has all wires running up the post and the plate is hard wired with a relatively short cable. Long enough to go from a gold plate mounted on the back of a camera but not long enough to go from the bottom to the top of a sled. So I called Joe Teodosio at AB - he an application specialist that was very helpful and ended up making me a custom plate and connection with plenty of extra cable.

Since I use Marshall and Nebtek monitors I just go right into the powertap on the plate and all is good but I'm sure you could put together a small voltage regulator if your concerned about your monitor. Good luck!

Thanks Kevin,

I'm probably going to go with the QR-XL plate you suggested since that is the camera I'm running. I am planning on selling my camera and upgrading to the new XL-H1 Hi-Def camera soon, and I think it has the same power requirements.

I do know a few electrical engineers that may be able to put together a small regulator for me, plus Anton Bauer has a plate for Panasonics 7" 12v LCD screen so I might see how compatible that is going to be for another brand with the same power consumption.

The engineers here at the studio I work at say that I shouldn't have a problem with the 14v AB batteries powering my monitor because they think the 14v rating for the batteries are "no load" ratings. They think the "load" rating will be well within my monitors capability to handle.

We'll see.

Thanks!

Are you sure, you want to go down the XL path. the lens is still internal focus and has no ability for follow focus or zoom... Big consideration on a steadi rig...

Check out the new JVC....

[Wade Francom]

Recently rethought my XL-H1 idea. Changing it to the JVC. Lower price, same performance, and a sweet lens to boot, follow focuseable. Now to get my tax return and sell my XL-1. Any takers?

[Trevor Crump]

Way to go....

[Tom Wills]

I'd just be cautious as I've heard from a lot of people that the JVC built in lens is terrible. I've also seen plenty of footage with huge Chromatic Abberations and some definite issues with clarity.

It may be a full manual lens, but that doesn't mean it actually works well. Just so you know, a new lens for the JVC is $12,000. That's the low-end one.

I'm interested in the Panasonic though.  1080p30 is just too incredible to pass up, as is the in-camera slow motion and fast motion.
