|Here is an example of a recent temperature altitude test project. The environmental conditions are in the table below and the unit is under full load conditions.|
Two devices under test. Note all input power comes in from the left, output connections to the loads go out of the chamber to the left and the loads are located outside of the chamber. All thermocouples exit the chamber to the left also. The units are sitting on a metal plate with heating and cooling elements under the metal plate while the mounting plate temperature is monitored on the top of the plate close to the devices under tyest.
