12 Thermal Performance
Full output power operation at room temperature is allowed only for operation time under
10 minutes. It is required to provide forced air cooling for operation at full power for more
than 10 minutes or for over-power tests.
.
In case of power components replacement it is important to insure a clean and smooth
surfaces for heat-sink mechanical assembly with thermal conductive grease between any
surface in contact, even for the isolation pad.
