Transformer / lamp driver, type LW20EU65-03, for Bio-UV ultraviolet disinfection systems. It supplies and regulates the lamp circuit; a unit that is failing typically shows as a lamp that will not strike, or one that strikes and then runs below its rated output, which reduces the delivered UV dose without necessarily raising a lamp-failure alarm. Bio-UV uses a number of different drivers across its range and they are not interchangeable, so match the type code LW20EU65-03 exactly rather than matching on wattage or appearance. Supplied by cBallast on quote-to-invoice terms; lead time and freight are quoted per RFQ against the destination Incoterm.
