to deliver 24 Volts to the device after ft, we suggest a power supply with at least
30.25 Volts and 0 Watts.
notice however that if the device delivered Voltage is increased from 24 Volts to 29 Volts
then with a distance of ft, we suggest a power supply with at least
34.17 Volts and 0 Watts.
a big savings in total power and far more stable.
notice how at these extreme conditions, a small change in input voltage has a big impact on total power.
