Product details

The Pentair 521171 is the external power supply for the IntelliChlor IC15 salt chlorine generator. It takes 115V line power and supplies the 24V the cell runs on. It is the genuine Pentair original equipment part.

What it does

A salt chlorine generator makes chlorine by passing low voltage current through the cell plates. The external supply is what converts household power down to the 24V the IC15 needs. When it fails, the cell has nothing to work with and the system goes completely dark.

Before you replace it

Confirm the circuit feeding the supply is actually live, since a tripped breaker or a dead outlet looks the same from the panel. If power is present and the IC15 still shows nothing, the supply is the part to change. It mounts outside the cell, so the swap does not involve opening the plumbing.

From Pool School

When to Replace a Salt CellThe life each manufacturer prints, what looks like a dead cell and is not, and choosing the next one. Read How to Clean a Salt CellHose first, acid only on scale that stays, and each manufacturer's own mix and time limit. Read

Questions and answers

What people ask about this product, answered by our pool techs.

Which system does this fit?
The Pentair IntelliChlor IC15 salt chlorine generator.
What are the input and output ratings?
115V input and 24V output.
Is it a genuine Pentair part?
Yes. It is the Pentair original equipment part, number 521171.
My IC15 is completely dead. Is this the fix?
It is the place to start. The external supply is what feeds the cell, so a failure there leaves the whole system with no power at all. Confirm the outlet or breaker feeding it is live before replacing the supply.
