Abstract (en)
[origin: EP1220581A2] A power supply device (1) for cold-cathode discharge lamps, constituted by a unit (2) for conversion from alternating-current mains voltage to direct current with voltage reduction, and by a distribution unit (12) which supplies power to one or more inverters (16) suitable to convert from low-voltage DC to high-voltage AC one or more cold-cathode discharge lamps (13). Appropriate devices (28) are also provided for diagnostics, programming, functional testing, any ground leakage, and identification of failure of the individual lamp. <IMAGE>
