A water-purification device (22) for a potable water system comprising a chamber (23) through which water flows, a plurality of light-emitting diodes (24) that radiate ultraviolet light into the water within the chamber (23), and a driver circuit (26) providing power to the light-emitting diodes. The light-emitting diodes (24) can be positioned within or outside of the chamber (23) and they can be electrically connected in series. The drive circuit (26) receives voltage from a power source (e.g., an onboard power source on an aircraft) and can include a feedback accessory (40), an input accessory (42) and/or a fault-status accessory (44).
