<p>Disclosed is a water treatment system adapted to be powered by an AC li ne voltage, the system including a housing and an ultraviolet bulb within the housing with a control circuit for providing power to the bulb, the control circuit adapted to be operated at a voltage lower than the line voltage. A voltage converter is provided for converting the AC line voltage to the lower voltage, the voltage converter being adapted to uniquel y convert the AC line voltage to the lower voltage and including plug means at the housing fo r connecting the voltage converter to the control circuit such that the plug means facilitate s interchangeable installation of appropriate voltage converters adapted to uniquely convert t he AC line voltage to the lower voltage. This invention permits the electronics package within the water treatment system to remain the same regardless of the line voltage/frequency as only t he DC voltage converter is different depending on the line voltage/frequency. The risk of serious electrical shock is vastly reduced and local electrical code approval is required only for the voltage converter and not for the treatment system itself.</p> |
