CE1000 250W Power Supply Safe Operating Area
Although the 250W PMU is capable of generating 250W of output power across a wide range of input voltages, caution must be exercised when operating from low input voltages. The difficulty with low input voltages is that the 28V Buck-Boost converter in the PMU is maximally stressed and generates a significant amount of heat.
Action Required: The firmware in each power supply should be updated to version 1.16 using the “Configuration Utility” app available for download at https://millswoodeng.com.au/250w_pmu.html. Then refer to section 4.5 of the 250W PMU Manual to enable the “Manage safe operating area” feature.
