Infrared Images

Toward the end of the cross-load tests, we took some photos of the PSU with our modified FLIR E4 camera that delivers 320x240 IR resolution (76,800 pixels).

The highest temperature our IR camera measured inside of the PSU was 72.7 °C, which is pretty low given our worst-case conditions.
