HP POE voltage range
Maximum voltage: 57V (safety consideration)
What is most optimum value for minimum voltage?
PoEp group objective; maximum power within practical limit (Power Dissipation, Safety consideration)
Power dissipation is function of the current
Increasing minimum voltage reduces current level for the same load power or
Increasing Power delivery to the load for a given current value.
Hence same infrastructure delivers more power to PDs for given PSE PS size and cost
Bottom line: more applications may supported
–Larger POEp market
