Product details

The Pentair IntelliChlor LT15 Replacement External Power Supply, 523753, is the LT15 Power Pack, the unit that converts household AC to the low voltage DC that drives the IntelliChlor LT15 salt chlorine generator cell.

Electrical

Pentair gives the power pack an input of 110 to 120 VAC, 50/60 Hz, 96 W (0.9 A) and an output of 28 VDC at up to 3.6 A. A 15 ft cord from the cell plugs into a 110 VAC outlet that is GFCI protected, and the power pack mounts on a vertical surface up to 15 ft from the cell. It has a fuse below the cell connection for added protection.

Fit

Pentair states that the LT15 may only be connected to the LT15 Power Pack (523753) or to a PC100 Power Center. Older IntelliChlor and iChlor power packs will permanently damage the cell electronics, so an older supply is not a substitute. The LT15 cell is 523741 and treats pools up to 15,000 gallons, producing 0.65 lb of chlorine in 24 hours at 100 percent output.

Installation notes

The power pack must be wired through a pump timer, electronically controlled switch, relay or automation system so the cell only runs while the pump is running. Pentair warns that chlorine gas can build up with improper wiring, and the cell should never operate without water flowing through it. Disconnect power to the power pack before connecting or disconnecting the cell.

From Pool School

Questions and answers

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

Which system does this power supply fit?
The Pentair IntelliChlor LT15.
Do I need to replace the cell as well?
Not necessarily. The power supply and the cell fail independently, so a system that has stopped producing chlorine may only need the supply.
Is it a genuine Pentair part?
Yes. It is Pentair OEM part 523753.
Will 523753 work with other IntelliChlor models?
No. This is the Pentair Power Pack, LT15. Pentair states the LT15 cell may only be connected to the LT15 Power Pack (523753) or a PC100 Power Center, and older IntelliChlor and iChlor power packs will permanently damage the cell electronics.
