Ultraviolet (UV) System Power Supplies/Ballasts

About Ultraviolet (UV) Power Supplies/Ballasts

Ultraviolet (UV) power supplies, also known as UV ballasts, are the electrical heart of any UV water purification system. These components regulate and deliver the precise electrical current required to power the UV lamp, ensuring consistent light intensity for safe and effective disinfection. Without a properly functioning ballast, even a new UV lamp cannot achieve full sterilization performance.

A reliable UV power supply maintains stable operation by controlling voltage and protecting against fluctuations that can shorten lamp life or interrupt disinfection. Over time, ballasts can degrade due to heat, moisture, or electrical wear—making timely replacement critical to maintaining your system’s performance. If your UV system’s alarm is triggered or the lamp fails to stay lit, it’s often a sign that the power supply or ballast needs replacement.

Aquatell carries a wide selection of UV ballasts and power supplies compatible with leading ultraviolet system brands, including Viqua and Luminor. These ballasts are designed to meet strict North American quality standards and are built for long-term reliability, ensuring your UV system runs safely and efficiently.
