OUTPUT DERATING
The PowerHub is both current limited and power limited. When operating below the nominal
output voltage, the current is constant and the maximum output power is reduced. When
operating above the nominal output voltage, the power is constant and the maximum output
current is reduced. Exceeding the PowerHub output ratings will cause it to not function
properly until corrected. Refer to Figure 2 for operation outside the nominal output voltage.
