Does a cp3 for use 12 or 5 volts?

Does a FPR on the cp3 use 12 volts or 5 volts for controlling it?

It is a current source, so the voltage varies based on the demand and the resistance of your particular FPR. If I were to guess, it would have an open-circuit voltage of 12V. However, I would not recommend hooking 12V (or even 5V for that matter) directly to the FPR.
