Overload Tests

Below you can see the maximum we could pull from this power supply. The objective of this test is to see if the power supply has its protection circuits working properly. We were unable to check whether the protections from the reviewed power supply were active or not, since we were limited by our testing equipment, which can only pull up to 1,000 W. During this test, noise and ripple levels were still extremely low, and voltages were still inside the allowed range, except for the +3.3 V output, which was at +3.09 V (6.36% below its nominal value).
