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, as it shut down when we tried to pull more than what is listed in the table below. During this test, noise and ripple levels were still below the maximum allowed and voltages were within 3% of their nominal values, except for the +5VSB output, which dropped below the minimum allowed, at +4.64 V.
