6 Cable Diameter (12V DC) and Transmission
Distance
The recommended transmission distances are for reference only, and the actual conditions
shall prevail. The following table shows the maximum transmission distance of cables with
certain diameter when the 12V DC power source voltage loss rate is below 10%.
For devices powered by direct current, the maximum voltage loss rate allowed is 10%. The
cables mentioned in the following table are all copper cables with electrical resistivity
.
In the following table, the unit for diameter is mm, and the unit for transmission distance is foot
(m).
