Thermal Regulation
This is an area where the Tramp differs from most 5.8GHz video transmitters on the market.
Transmitters of this size and weight class, which shed the traditional heat-sinks used to keep
electronics cool, need to protect themselves against overheating by being a little smarter.
The Tramp HV continuously monitors the internal temperature, and regulates the power output in
several steps until the temperature is within safe limits.
This practice ensures that the components used in the transmitter are not used outside of their
maximum operating conditions, and will eliminate premature failures.
When in a reduced power output mode, as soon as airflow is present, the transmitter will quickly
increase power output to requested levels.
When is this useful? Imagine a quad sat on the starting grid of a race for several minutes, as other
pilots get ready, props stationary.
The Tramp HV will lower its power output until a safe level is reached. As soon as the quad takes off,
the airflow from the props will quickly cool the transmitter, and increase power output before the
quad reaches a distance from the pilot where full power is required.
Note that as with any high-power video transmitter, ensure that adequate airflow is available when
a model (whether it be a wing, or a quad) is in normal flight.
