What are good Power options electronic follow focus?

[PatrickFaith]

Thanks all for a bunch of great threads on electronic/remote follow focus!

I'm now trying to figure out the best way of powering a follow focus receiver. (I'm purchasing a fstop wireless receiver btw)

For large cinema lenses, i have noticed the amp ratings can be fairly high (i.e. powering a heden, or even multpile motors on one receiver).

I'm one of the Scarlet crowd, been around awhile, but this is my first foray into the camera side, and I find the entire accessory power options super confusing.

I've seen a lot of the very high end options (i.e. where the power system costs more then my scarlet), and I don't want to get a low end power options(thus end up just rebuying).

Using red power/battery stuff seems like an option, it seems perty expensive to power accessories ... I'm really looking for something solid and cheap. My camera is always on a tripod/jib/dolly so I'm not so much worried about weight, but things get to be a hassle when the camera is way out on a jib.

Any suggestions on low end vs high end are welcome (i keep purchasing low end on stuff, then realize i have to re-buy as i'm in production and things aren't going so swell). I guess i'm rambling ... which goes to say how confusing I find the power options on high end camera's(I did power systems on spacecraft for a few years, I swear the power systems in cinema are more complex).

Hey Patrick,

Take a look at our powerPack. While it's part of our ultraCage system, there will be a bundle that can actually be used independently in any situation due to the 1/4"-20's that surround its back. It can take in an input of 12.5-15V (Supplied by really any source, on the less expensive end a Switronix Battery), and has two 12V outputs (regulated or unregulated) as well as a variable voltage output that can supply out any specific voltage from 5V to 12V, most commonly used for the camera itself.

It's a really universal piece that will always be relevant no matter what accessories you have or camera you'll be using, as pigtails are available for your slicing and dicing pleasures.

Thanks much ... I was actually studying the powerpack today, I really liked the idea of a universal power bus, it makes sense integrating various power systems(it's actually how I kind of think of power). The Switronix battery also makes a lot of $ sense, since I can use that for my scarlet. I am going to draw something up, make sure I "get it" after I talk with the accessories people(i'm perty sure the P-TAP cable included will connect to the fstop p-tap cable option) . Is there an option to connect the powerpack to a scarlet (i.e. power both the scarlet and my accesories from the universal power bus) - that would be super nice?

Since the Scarlet can accept an input ranging from 11.5V to 17V, you could actually use one of the 12V outs, and still keep the variable voltage free for an accessory that may not have an internal regulator. So here's how I would break it down probably:

Output 1-FStop Digital Receiver-12V Regulated
Output 2-Scarlet-12V Regulated
Output 3-Anything- Variable Output (I really like this output, because since you can control the voltage out you can really attach some unconventional things to this port by using the pigtail we can provide)

As for the P-TAP included, yes that is what you'll need to feed into the powerPack from any professional battery system, however, in that bundle you'll also be receiving a cable to power the C300, so I would hold off until we get the generic SKU up.

Hey Patrick,

Although this may be more than you need at this time, I just wanted to share this power package as a reliable alternative for powering your camera and accessories using the same source. The ActionProducts power solution also maintains low weight and high maneuverability, and can power all your accessories as well as be hot swapped on the set.
