Toto D Guerra Posted April 23, 2017 Share Posted April 23, 2017 Hi, I wanted to share the following measurements I did on my SR-3 camera package. Might come handy when you're trying to determine your battery needs and expected turnaround on set, and/or for those who have battery recell projects like me currently. . Idle: 0.09A . Idle + IVS: 0.40A . 24fps: 0.35A . 24fps + IVS: 0.67A . 75fps: 0.65A . 75fps + IVS: 1.01A (2.00A peak charge at start) . Idle + RCU-1: 0.12A . 24fps + RCU-1: 0.38A . 24fps + IVS + RCU-1: 0.72A . 75fps + IVS + RCU-1: 1.05A Best, Toto 1 2 Link to comment Share on other sites More sharing options...
Premium Member Dom Jaeger Posted April 23, 2017 Premium Member Share Posted April 23, 2017 Hi Toto, Thanks for taking the time to post your measurements! Can I ask if you measured the current draw with a loaded mag, an empty mag or just the body? It makes a little bit of difference I've found. My (possibly faulty) memory of SR3 specs is a draw of about half an amp with a 400' load at 24fps. A simple way to remember the accessory draw is that an IVS basically draws about a third of an amp regardless of camera settings, while an RCU unit pretty much draws nothing. 2 Link to comment Share on other sites More sharing options...
Toto D Guerra Posted April 24, 2017 Author Share Posted April 24, 2017 Hi and thanks for your response, I did the measurements with an attached empty mag. The measurements would be different with actual film in there and thank you for asking for clarification. I might find expired film and redo the tests then, I'll update this post when I do so.
