Unitrack Switch Controls with MRC Controllers?

[scott]

I'm thinking of using MRC 220 or 260 controllers rather than the Kato controllers with our Unitrack DC layout, since the MRCs are about the same price and have momentum. But I still want to use the Kato switch controllers, which means I'd need to connect the Kato AC/DC converters to the MRCs.

 

The thing is, the Kato converter is for 16 or 17 volts AC, but the manual says that the MRC controllers have 18.5 volts AC output. Is that a big enough difference that it wouldn't be safe to use this combination?

 

Thanks...
