Question emailed to me Today

[Smjh1979]

I don't know how to answer this. A few people on here should know more than I do on this subject:

This person has been trying to figure out a range for power requirements for a railroad crossing, including all necessary components.

Anyone got an idea?

Basically 10 volts for the lights, nominal 12 volts for the crossing controller, 16 volts for the gate mechinisms, and of course 110 volts AC for the power supply and/or charger(s)
