wiring?

[Anonymous]

I would like to know how to wire all my MRC Tech4 220 power sources together for AC. Is it possible to do this with out increasing the voltage or damaging the power source. This is only for the AC side only. I am trying to keep the load even on all power sources.

First of all, I need to know which AC you are referring to. If it is the 120V line voltage, you most certainly can run them in parallel. If it is the low voltage or secondary voltage, would not recommend it. Slight voltage variations will result in heat loss and internal heating of the transformers. You can use several power supplies but route each transformers AC output to separate devices. For instance use one for street lights and another for some switch machines and another for more switch machines.
Hope this helps,

Thanks , 16.5 AC. Ithink you answered my question. I thought I could do this. However you have indicated it not to be such a good idea. All supplies are the same.

It is definitely not a good idea,never with AC.

This will also cause a problem on the DC side of the throttles. By wiring the AC transformers in parallel you have one large transformer. Check out Rob Paisley site http://home.cogeco.ca/~rpaisley4/CircuitIndex.html#Pageless to see why one transformer cannot be used for two throttles. Good site on many topics.
