Am not into DCC but am wondering about DCC decoders in MTL F-7s. A wiper user now wants to go DCC and was asking me about this:
The standard decoder outputs 12 volts. Too high for 8 volt MTL motor rating and some concern about burn out. It appears that ZDCC installs can and do get away with the 12 volts without problems.
Does anyone make a DCC decoder specific to Z scale with reduced output voltage?
Has any DCC user ever damaged a Z motor with 12 volt decoders?
Is it possible to reduce the AC voltage to the main power source (booster?) to reduce the track voltage and still have the system work?
Assumimg there is lots of room, such as the decoder in a drawbar-coupled and wired dummy B unit, has anyone tried 2 paralleled strings of 6 silicon diodes in series to drop a constant 4 volts between the decoder and motor? Or 2 x 3.3 volt 2-5W zener diodes in series to do the same thing?
