Cooling Management on the fan unit (Lifextender) ®
In respect to the current cooling requirements, the fan speed rotation is adjusted from a
minimum of 60% to a maximum of 120% approx� (these values may change according
to the models of used fan)� The cooling demand evaluation is based on accurate mea-
surements of the temperature close to each MOSFET and to the power supply units� The
Cooling Management aims to:
1� extend the life of the fans;
2� minimize the quantity of dust which can be carried by the air flow;
3� allow the safe operation of the equipment also under extreme temperature condi-
tions;
4� ensure that temperatures of mosfets and power supplies remain as stable as possible
to avoid thermal and mechanical stress;
5� reduce the energy consumption when a strong heat extraction is not needed�
Without Lifextender, the fans always operate at 100%�
4.3.2 Hardware protections
The hardware protection system comprises:
• fast electronic and fuse protection for power supply units;
• fast electronic protection on the fan power supply;
• fast protection against excess reflected power (SWR/VSWR) following a strong load
mismatch�
This protection is activated when the reflected power value exceeds 10% of the direct
one�
The LifExtender can be requested as an option using the previous codes� To be specified
in the order�
