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. This unit passed this test, since it shut down when we tried to pull more than what is listed below. During this test, the +3.3 V and +5VSB outputs presented voltages below their minimum allowed values, at +3.02 V and +4.74 V, respectively. Noise and ripple levels were still extremely low.
