| Jul 15, 2021 at 11:52 | comment | added | Bimpelrekkie | ..the relations between voltage, current, power and resistance. Using 48 V and a couple of Ampere (so less than a few hundred Watt of power) you can practically span a distance of less than 10s of meters. I mean, 100 meter would already mean a lot of power loss. There is a reason why electricity is transported at for example 110 kV and higher: to keep currents low and thus keep the losses low. | |
| Jul 15, 2021 at 11:51 | comment | added | Bimpelrekkie | What I am trying to essentially do is figure out what my limitations would be for sending 48V DC as far as possible You can send 48 V over practically any distance you like as long as there is no current flowing. But no current means no power (Power = voltage * current). "As far as possible" What does that mean? 48 V and a certain power means a certain current. That current in combination with the resistance of the wires and how much voltage drop you can accept will limit how long the wires can be. If you want to understand this better you need to study ... | |
