This Power Supply Module is the perfect mounting and power solution for the DJI Video Transmitter or Receiver. The front and back plates of the module can be installed on both sides of the video transmission units. The front side of the module allows you to mount your DJI Video Transmitter or Receiver to a V-Mount Battery Plate on your camera system. The back side then allows you to mount a V-Mount battery to the unit which can provide power as well as pass power through the module to the camera body or wireless monitor. This is a fantastic option for those who are looking for a clean and convenient way to mount and power the DJI Transmission System.NOTE: These Plate can only mount to the transmitter in one configuration which will position the SDI ports on the Operators side and the LCD Screen/Control Knob on the Assistant's side.
