My TIU cable lengths are:
Tiu-AIU1 = 12ft
AIU2 = 12ft
AIU3=12ft
AIU4=20ft
AIU5=15ft
I have purchased a 12VDC regulated power supply at 2.5amp. I have an adapter that will convert the plug to screw on wires. I was going to run 18ga wire from my power bar (where I have a few transformers plugged in) to the location of AIU5, which is about 25ft. There I will have a terminal strip to take the 12VDC to the two AIU wires needed for the 6 wire cable connection.
I will check for polarity. Do you think the 2.5amp transformer is OK? I was going to also use the same transformer to boost the signal on my track detection boards for running the Hikel system.
Alternatively, I could use individual 1amp power supplies, but I thought combining them would be better, as both AIU5 and the signal boost I need for my NCE track detection AIUs are at the same location.
Please let me know if you think this transformer is OK at 2.5amp rating. My understanding is the MTH AIU will pull the load it needs, so as long as the transformer can supply the required amps, extra amps will go unused.
