Ratelco is a name I have not heard in a long time.  Ratelco had a couple businesses that split over time.  Radio site management still exists in Seattle area, radio installation and repair including Motorola depot repair, I think this was acquired in the recent past, and a telco power systems division.  I happen to have worked for the power systems division as one of the few engineers there for 3 years in 1987-1989.  In the early nineties the Power Systems Division was acquired by C&D Technologies.  I doubt you will find any transformer info online as they were designed and built inhouse before the internet age, assuming this unit is from that  era.  So you might try contacting C&D Technologies for info.

Morning - Sorry for the OT request but maybe someone can help.  I'm 
collecting parts for a K3 analog power supply and have come upon two 
large unknown Ratelco, Inc transformers.   I've tried and about given up 
searching the net for information.
 
Ratelco, Inc. part number 2045 and is a transformer with several 
windings.  One set very heavy current.
Ratelco, Inc. part number 2590G and is a large choke of some current 
capacity.
 
Any information, especially current ratings, would be appreciated.
 
Thanks
