Technical Information
Output Power during High Temperature Condition (derating)
An example of the trend of the derating curves implemented to
optimize the vacuum performances is reported in figure 35.
Figure 35 Example of a power limit curve
Furthermore, the final power limit curves also minimize mechanical
stress to extend the pump reliability through a smart rotational
frequencies management.
