Electrical Wiring in the Home/Multi voltage Transformers Generic


My three wire transformer (red blue yellow) Part No. 628398 has burned out.  Other data: Input 117V AC 60Hz 15W; Output blu/yel 24.5V AC AT 31A. red/yel 9.vV AC AT 15A.  The transformer is used on fairly old RainBird six station PC-106 unit. I have not been able to find an exact replacement on any of web sites including the RainBird web site.  My question:  I wonder if there is a universal transformer that might work?  Thanks.

Yes there should be a transformer that has dual secondary outputs       yellow is a secondary common tap,  used with blue for 24.5 volts, and with red for 9 volts,  you need 115 to 120 rated primary input,    it need not be exact,    I CANNOT imagine this controller having some kind of exact input voltage,    it would depend on the utility voltage,  a manual if you need one in pdf format,

above are some replacement controllers    and some lighting transformers,  you need a fixed primary with a dual secondary,     one for 24 volts and one for 9        the 24 is for the main valve,  and the 9 is for individual valves/taps

above is a  variety of generic multi tap transformers,

You need a standard multi tap transformer  dont be confused because it says  lighting     all you need is  31 or 32 amp capable  with two or more secondary taps, any electrical supply house should have what you need,

We can always rewind the transformer,   it is probably not cost effective, but it can be done,      our shop is MEAR Services Inc,   Kansas City Missouri,  phone is 816-650-4030
