PoEp Power Architecture-AC UPS

 Cost of power supply with 44V or 51V outputs is approximately the

same. But under the same conditions, 51V output power supply will

have higher efficiency then 44V PS

 Estimated cost of additional boost circuitry for supporting the change

from 45V to 52V for 500W power supply is about 10% cost of power

supply.
