Logbook!
That is the most authoratative and relevant response yet to date. Can you tell me if the standard series voltage regulator you are refering to, adjusted down to a peek of 17 Volts, would pass 12 volts Ok when the batteries drained down to that level?
Dear nbuska,
You are quite correct.....
The radio receiver is operating off of a fraction of that current but it is controlling the variable voltage circuitry that changes the motor's speed.
The radio receiver circuit (or decoder) has only one voltage input to the board......up to 18V and 10...
By the way...an additional note to Logbook....
I don't really need all 18V to run my trains. I could live with 16 or 17 volts. When combined with the new lower restriction that the 8 amp fuses enforces, could I find a zener that would do the job for the short time that these batteries will be...
Hey everyone....THANK YOU for all your replies.
Here is a bit more information.
The "delicate circuit" I am trying to protect is in fact a "radio control throttle receiver". In other words, the full 18+V is fed into this device and, by means of a handheld radio control transmitter, I can vary...
I need to insert a component or a VERY simple circuit intoa project that will limit DC voltage to 18 volts (I could use 16 or 17 volts too, but nothing more than 18 volts).
I don't want a voltage regulator because the voltage wil be running small motors and must vary from 0V to 18V, but if it...
