Abstract

A ballast module, for powering UV lamps in a fluid treatment assembly, that has electronic ballast with a high resonance frequency. The high resonance frequency reduces the size of the components so that the ballast module can be mounted in proximity with the UV lamps where the ballast module is also cooled by the fluid being treated by the UV lamps.
