    24V on Steadicam Zephyr

    Hey all, I've been operating for almost 8 months now and this is my first post here. I'm tasked with flying the Arriflex SR3 on my Zephyr and I know I have to get some attachments to be able to do that. From my understanding I need a second battery plate with the ability to switch between serial and parallel in addition to cable adapters for the camera. However, when I searched Tiffen for any official 2nd plate for Zephyr I couldn't find any. I've been scouring the forums to find anything of use and I've found some stating that the Zephyr is able to fly 24V with some attachments, since everything else is already wired in - but that's pretty much it. Is there anywhere else I could find a suitable plate and is there anything else I am missing? Please correct me if I'm wrong and hit me with your wisdom. Thanks.

    Zephyr 2nd Battery Plate

    Hi-ho, everyone. Anyone know if there's anything particularly special about the official Tiffen 2nd Battery Plate for Zephyr besides the 12V/24V mode switch? I have some spare parts lying around: - AB plate with D-Tap - Threaded cheeseplate - D-Tap to 3-pin LEMO cable And I was thinking if I simply attach an AB plate to the cheese plate to the bottom of the sled (where the second battery plate would also attach) and plug from D-Tap to 3-pin LEMO IN on the sled base to,swill that give me the equivalent of 24V mode or 12V mode?

    GPI PRO CineLive 12v vs 24v output for cables

    Hi yall When we flip the CineLive into 24v for using ARRI and other cameras, do the upper electronic switch out to 24v exclusively? I am having cables made for a Chrosziel MagNum receiver and am wondering if I need a 12v and 24v cable, or 12v only. The receiver does not care whether it receives 12v or 24v, it will push voltage independent of whats coming in. Try as I might, I have a difficult time understanding electricity. brett.
  6. Hi all, I own a Shadow sled and I'm mostly flying Alexas in 24v mode. Instead of switching two 12v batteries in series I have had a 24v battery plate made to Chris' example. http://www.steadicamforum.com/index.php?showtopic=14350 It allows me to attach the 24v batteries that come with the camera on the bottom of my sled and supplies the 24v system. A neat feature of the shadow sled is that it has a DC/DC step-down converter built in to convert the 24v to 14.4v (or something in that neighborhood) to supply the 12v system with power while simultaneously powering the camera with 24v. This is where my problem comes in. I'd like to use one of my 12v batteries on battery plate nr.1 to supply all the 12v systems and the 24v battery on the bottom battery plate nr.3 to solely power the camera and nothing else since the Alexa is hungry enough. What happens now is that as soon the 24v batt is attached it powers the DC/DC converter, even when I have my sled switched off. At some point when the voltage of my 12v batt drops low enough I assume the DC/DC system starts charging my 12v batt. I figure the best solution to meet my wishes is to switch the DC/DC converter off so it doesn't help power the 12v systems and more importantly doesn't start charging my 12v battery. Does anyone know if there is an elegant way to achieve this? I opened up the battery plate of the shadow sled to check out if it could be a simple solution but it looks quite complicated :-) Your insights are much appreciated. Cheers, Jelle.
  7. Does anyone know the connector brand, part number and wiring for 24 volt acessory power connectors on Arri cameras? Is there any kind of standard or most used type for 24 power among the various camera brands and models, or are they all different? and... is there a good source for lemo and other types of connectors for cameras? Thanks!

    Alternating voltage problem

    Hey guys, I have a custom top and bottom stage on my rig (wired by Terry West), and am wondering if you guys could help me figure out an electrical issue. Before you dismiss me and tell me to take it to Terry, I've been working on this with him also, but figure I'll cast a wide net for answers. The issue is that my camera power has a tendency to drop out, and it seems pretty much at random. Its both the 12v and 24v power. Whats strange is that the power doesnt drop all the way out- it just drops from 14.4v or 24v to about 9v, and will shift back and forth from one to the other, but never anywhere in between or lower. Sometimes this shift is very quick maybe just a few seconds, and sometimes it will be minutes. Obviously this shuts down any camera that is being powered by the rig, so I have resorted to powering things on camera for quite some time while trying to figure this out. I went through and spread the pins on the post (XCS post) to make sure each connection was nice and solid in the post / bottom stage connections, but the problem is still persisting. I'm not really an electrical engineer, so before sending this in to Terry one more time I was going to open it up here and see if anyone has a good idea. Hit me with your best shot! I'm stumped. -TJ
