Product Overview

The Pentair BioShield UV Disinfection Sterilizer Multi-Voltage Power Supply | 523032 is a genuine OEM replacement ballast/power supply designed for select Pentair BioShield UV Disinfection Sterilizer systems.

The power supply is a critical electrical component responsible for delivering the proper operating power to the UV lamp. If a compatible BioShield UV system has stopped illuminating the UV lamp, experiences intermittent operation, or has a failed original ballast, replacing the power supply may restore normal system operation.

Pentair part 523032 was used with previous-generation 50W, 80W, and 120W BioShield UV systems. It is specifically listed for BioShield models 522635, 522636, and 522637.

Because Pentair has revised the BioShield product line over time, customers should verify their UV system model, revision, and existing ballast part number before ordering.
