MATEN 5.8G 2.5W VTX PRO has very powerful performance. It has 5 adjustable power levels and the maximum power can reach 2500mW. The transmission signal is very stable and the penetration ability is excellent. MATEN 5.8G 2.5W VTX PRO uses high-strength aluminum alloy CNC to assist heat dissipation. appearance design and active fan cooling provide stronger impact resistance and better heat dissipation performance. It supports the Tramp protocol and can use the OSD to quickly adjust parameters. The built-in microphone can transmit the sound of the aircraft in real time. 7-36V wide voltage input, with temperature control protection function to prevent overheating and burning. Supports two mounting hole positions: 20x20mm and 30.5x30.5mm. Built-in micro-type turbo fan for active cooling One function adjustment button and three indicator lights, easy and fast operation Image transmission control protocol Tramp, supports OSD parameter adjustment Product name:MATEN 5.8G 2.5W VTX transmission Installation hole position:20x20mm(M2), 30.5x30.5mm(M2) Output power:25mW/200mW/600mW/1600mW/2500mW/Pit mode Frequency:5.8G Number of channels:48CH Input voltage:DC7-36V (2-8S Battery) Output voltage:5V@600mA Control protocol: Tramp Antenna interface:MMCX Cable interface:SH1.0 6pin Video format:PAL/NTSC Microphone:Built-in microphone Weight:17 grams Precautions 1. Install the antenna before use. 2. If the image transmission overheats, the temperature control protection will be activated and the power will be automatically reduced. Please good ventilation and heat dissipation when using it. When the environment is limited, you can install a cooling fan for the image transmission. 3. The 5V output is only for the camera. It is prohibitedto connect the power input terminal to the 5V output port, otherwise the image transmission will be damaged.
