MXS System Description and Installation Manual UM06945

• (a) device on insulated closed-cell foam pad, natural convection only on top and side surfaces.

• (b) device on insulated closed-cell foam pad, ducted forced air cooling at 20.1 LFM on top and

side surfaces.

The temperature protection limit at 110 °C applies to the average internal device temperature. The

average device temperature is representative of the majority of PCBA components within the device.

The SoC within the device typically operates at a temperature delta of ~10°C above the average device

temperature and triggers overtemperature protection at a correspondingly higher temperature of

120°C.
