3R System AK6-500M Power Supply Review
Overload Tests
Contents
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 we couldn’t pull more than shown in the table below because the power supply would shut down, showing that its protections are present and working well. During this extreme configuration, noise and ripple levels were higher than the maximum allowed: 142.8 mV at +12VA, 167.8 mV at +12VB, 61.8 mV at +3.3 V, 51.6 mV at +5VSB, and 228.8 mV at -12 V. The +5 V output was the only one with noise and ripple levels within specs (at 26 mV).
