The Pentair 521233 Load Center System Transformer supplies the low-voltage power that runs the control board, display and accessories inside a Pentair load centre.

Frequently Asked Questions
How do I know if I need the before or after change-date version?
Match the part number printed on your existing transformer. The earlier version is 520722; this 521233 fits load centres built after the revision. Getting this wrong means a part that will not mount or connect correctly.
What are the symptoms of a failed transformer?
Usually a completely dead panel — no display, no relay operation, nothing responding — after you have ruled out breakers and incoming supply.
Is the enclosure included?
No. This is the transformer only.
Will this fix an IntelliChlor that has stopped working?
Possibly, if the whole panel is dead. If only the salt system is affected, look at 520722 or the SCG board instead.
Does it come with mounting hardware?
It is designed to fit the existing bracket and harness in your load centre.
Can I replace it myself?
No. Load centres carry line voltage and this work should be done by a licensed electrician or qualified pool technician.
