Ripple Measurements

In the following table you will find the ripple levels that we measured on the main rails of HALE90 750W. According to ATX specification the limits are 120 mV (+12V) and 50 mV (5V & 3.3V).

Ripple Measurements
Test	12 V	5 V	3.3 V	Pass/Fail
20% Load	11.2 mV	10.2 mV	5.2 mV	Pass
40% Load	15.2 mV	11.8 mV	6.0 mV	Pass
50% Load	17.0 mV	13.0 mV	7.4 mV	Pass
60% Load	19.2 mV	14.2 mV	9.2 mV	Pass
80% Load	23.6 mV	17.4 mV	14.2 mV	Pass
100% Load	27.6 mV	19.6 mV	19.8 mV	Pass
Crossload 1	19.2 mV	14.2 mV	8.8 mV	Pass
Crossload 2	25.8 mV	19.6 mV	20.8 mV	Pass

The quality of the DC outputs is very good. More specific, ripple/noise suppression at +12V is outstanding while the minor rails are also doing fine here, since they stay near 20 mV at worst.

Ripple at Full Load

In the following oscilloscope screenshots you can see the AC ripple and noise that the main rails registered (+12V, 5V, 3.3V). The bigger the fluctuations on the oscilloscope's screen the bigger the ripple/noise. We set 0.01 V/Div (each vertical division/box equals to 0.01V) as standard but sometimes we are forced to use 0.02 V/Div, meaning that the fluctuations will look smaller but actually this wont be the case.
