Cross-Load Tests And Infrared Images
Our cross-load tests are described in detail here.
To generate the following charts, we set our loaders to auto mode through our custom-made software before trying more than 25,000 possible load combinations with the +12V, 5V and 3.3V rails. The load regulation deviations in each of the charts below were calculated by taking the nominal values of the rails (12 V, 5 V and 3.3 V) as point zero.

As you can see, the SSR-650TD offers higher than 94% efficiency across a significant part of its operational range. This is a remarkable feat, even for a Titanium-rated unit.
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).
Temperatures inside the PSU are normal, given the very low fan speed and semi-passive mode. High efficiency definitely helps minimize the thermal output.
