Overload Tests
Contents
Below you can see the maximum we could pull from this power supply. Keep in mind that each +12 V input of our load tester is limited to 33 A, and that is why we couldn’t pull even more power from this unit. If we tried to pull anything about what is described in the table below, the unit would shut down immediately. Also, we couldn’t pull more than 21 A from each +12 V rail because the over current protection would kick in, which is great to see. During this extreme configuration, noise and ripple levels were still extremely low, in the same range as test five (see previous page). The +12 V and +3.3 V outputs got outside the tighter three percent regulation but were still inside the appropriate range. (+12VA at +11.64 V, +12VB at +11.44 V, and +3.3 V at +3.17 V).
