The OCP triggering points at +12V and 5V are quite low, while at 3.3V it is sky high allowing the voltage to drop as low as 3.11V. Obviously this needs to be fixed.
The unit's OPP is set at 1368.84W and given the problems that the +12V rail faces at high loads, this is above the platform's capabilities. For the moment, though, a 130% OPP threshold is ideal, so Enhance Electronics should fix the +12V rail's performance issues when dealing with load over 95 Amps.
The over temperature protection is also working well and there is short circuit protection on all rails. Unfortunately, as we mentioned the power ok signal is not accurate, which is a shame especially for a high-end product like this one. Lastly, there is an MOV providing protection against spikes coming from the mains grid and an NTC thermistor along with a bypass relay to protect from large inrush currents.
