Running a TV-logic VFM on V-lock battery
Posted 15 January 2012 - 08:14 AM
I was wondering if anybody already tested if you can run a tv-logic VFM-056 on a v-lock battery.
The monitor is rated 7 to 12V and V-lock batteries output, depending on the charge, something between 12 and 17V... So theoreticly that would be to much power.
Any hands on experiences?!

I own that monitor too and upon speaking with a TV Logic engineer, I learned that the true voltage limit is 15v. Often freshly charged bricks can run as high as 18-20V, which is enough to fry the monitor. Often you'll be ok, but there is a risk.
Best to use a power regulated cable if coming from D-Tap, or if the brick is also powering a camera, pull the plug on the monitor and let the camera power up, then plug the monitor back in.
I had a cable made with an inline 12v regulator that has a Fisher 3 to D-Tap jumper, so it can do either safely.
