6 Cable Diameter (12V DC) and
Transmission Distance
14
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).
