Overload Tests

Below you can see the maximum we could pull from this power supply. Because of its incredibly overspec’ed components, we could easily pull 1,000 W from it. In fact, we had to stop our test at 1,000 W only because this is the limit of our load tester, and this power supply may be able to deliver even more. During this extreme condition, efficiency dropped to 82.4%, but noise and ripple levels were still extremely low and voltages were still within 3% from their nominal values.
