Protection Features Evaluation

The OCP triggering points are higher than 130%, and the OPP is set pretty high as well. However, it is great to see separate OTP circuits for the PSU and the Connect module.

DC Power Sequencing

According to Intel's most recent Power Supply Design Guide (revision 1.4), the +12 V and +5 V rails must have voltages equal to or greater than the +3.3 V rail's output at all times. For our first measurement, we turn the unit off and switch it back on without a load on any of the rails.



No problems here.

EMC Pre-compliance Testing - Average and Quasi-Peak EMI Detector Results

Electromagnetic Compatibility (EMC) is the ability of a device to operate properly in its environment without disrupting the proper operation of other close-by devices.

Electromagnetic Interference (EMI) stands for the electromagnetic energy a device emits, and it can cause problems in other close-by devices if too high.



EMI noise is increased at frequencies below 1 MHz.
