Balboa Water Group Transformer 6 Pin 220 Volt / 15 Volt 30270-2

 

Which transformer do I use 110 volt or 220 volt?

It can actually be either... PC boards do not necessarily come one way or the other... The ones we sell are 240 volt input which would be the 30270-2... Do you have a neutral wire? If no neutral that makes it easy (30270-2) If you DO have a neutral it can still be either one unless the neutral runs to one of the two bottom fingers on the board (which means you would use 110 volts P/N 30270-1)

Input voltage is White and Blue.
Output is as follows:
From red to yellow 7.5 volts
From red to brown 7.5 volts.
From yellow to brown 15 volts

All readings in AC
