Re: D-tap voltage

Re: D-tap voltage

On my Movi Pro gimbal, where I use DJI's TB50 batteries, I have a special cable made that runs an extra D-Tap output straight off the batteries. It’s 26 volts, not the standard 12-16 volts, so I have to be careful which accessories I plug into it.

I chose a D-Tap connector for this accessory cable because I own so many D-Tap cables in my kit, but the battery plate also has a Lemo output if I want it. The Movi only offers a limited amount of current draw through its built-in D-Taps, so I mostly use this as an additional accessory port.

Most accessories these days, like wireless focus MDR’s or wireless video transmitters, are tolerant up to 30V, so they work very well, but some aren’t. For example, Preston MDR 3 and 4 are 30V tolerant, but the older MDR2 is 12V.

I don’t usually run the camera from this 26 volt port, but RED’s are 11.5 to 17 volts only, while Arri is happy with 10.5 to 30 volts.

Best,
-Graham
