LEPA G850-MAS 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 it shut down when we tried to pull more than what is listed in the table below. However, noise and ripple levels were way above the maximum allowed at the +12 V (above 460 mV) and -12 V (above 450 mV) outputs. On the other hand, all positive voltages were still within 3% of their nominal values.
