Power and Transformer Calculator
Size a transformer and check voltage drop along a cable run, so far fixtures stay bright.
A planning estimate for a 12 volt system. It treats each run as if all its load sat at the far end, which is the cautious case. Real layouts spread the load and tap the cable, and we size every system on site.

Questions
About the power and transformer calculator
Is this the exact voltage?
It is a cautious planning estimate that puts the whole load at the far end. Real layouts tap the cable in several places.
Why leave headroom?
A transformer that runs near its limit gets hot and wears out sooner, and leaves no room to add lights.
What if the drop is too high?
Heavier cable, shorter runs or an extra tap point fixes it, and we plan for it.
