Balboa 30270-1 120V 6-Pin Transformer

Replacement power transformer for Balboa Standard/Deluxe 120V spa control boards – Balboa Water Group 30270-1; also used on select Sundance systems (cross-ref 6560-278). It steps line voltage down to low voltage for the control circuits and connects with a 6-pin plug. Confirm your pack uses the 120V input version with a 6-pin connector; it won’t replace 230V models.
