C.1: Operating Temperature and Cooling Configurations
The following charts show the maximum allowable ambient temperature of Xenus amplifiers for a
variety of operating conditions and cooling configurations. The cooling options are for Xenus
amplifiers with no heatsink, with the low profile heatsink and with the standard heatsink all with
and without forced-air cooling. The operating conditions considered cover a range of continuous
output currents at both 120 Vac and 240 Vac mains voltages.
