I'm setting up two additional loops with a spare (old) TIU.
Two potential power sources are on hand that are not on MTH's recommended list (i.e,not in the operators manual)
#1 MRC Dual Power 270 watt transformer.
#2 Lionel 180 watt Powerhouse power supply.
Can I use either as track power thru the spare TIU? If not, then why. I've already used the MRC for several hours and have had no issues with it so far, but invite comments/cautions. I think this one was advertised as pure sine wave.

I use the MRC, no problems in last 6 years.
If I needed more power I would use the powerhouse bricks, lots of others on here do.
Bob,
Both of them should work fine with DCS.
However, I would suggest that you use an external breaker or fuse, in the Hot wire between the transformer and the TIU channel input, for each TIU channel that you use.
The fuse should be of the 10 amp, fast-blow variety and any breaker should also trip immediately when draw exceeds 10 amps.
I'd use the PowerHouse 180. It has a lightning fast 10A electronic breaker, the MRC Dual-270 has thermal 7A breakers that are not nearly as fast.
With the PH180, no need for extra protection between the transformer and the TIU.
