Ripple Measurements

In the following table you will find the ripple levels that we measured on the main rails of CSP-X1200CB. 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	7.2 mV	4.8 mV	4.8 mV	Pass
40% Load	9.8 mV	5.2 mV	5.4 mV	Pass
50% Load	10.8 mV	5.6 mV	5.4 mV	Pass
60% Load	12.8 mV	6.0 mV	6.2 mV	Pass
80% Load	18.8 mV	6.8 mV	8.0 mV	Pass
100% Load	24.2 mV	9.4 mV	11.2 mV	Pass
Crossload 1	8.8 mV	5.2 mV	4.4 mV	Pass
Crossload 2	24.2 mV	8.4 mV	11.6 mV	Pass

Ripple is very low on all rails and throughout the whole load range. Even when we pulled 1200W from the unit, ripple didn't exceed 25 mV at +12V. A very low reading which shows that Andyson mastered the ripple/noise suppression, at least with this platform.

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.
