Fasar Elettronica has designed a system with high efficiency, which makes use of a half bridge structure and a dedicated integrated circuit, for driving a UV-C lamp of 16 W with 4 pins. The electronic card, which can be supplied assembled in a practical plastic case and possibly already equipped with UV-C lamp, must be powered from single-phase network.
It is possible to change by the hardware the output frequency and the preheating time; protections are also implemented in case of critical conditions (open filament, lamp absence) that force a shutdown of the power supply.
A bicolor led provides information about the operating state of the power supply (green light to signal the correct functioning of the system, a red light to indicate a lamp failure). The proposed system has found use in the food sector and, in particular, in the preservation of food.
System to control a UV-C lamp of 16 W: the ballast power supply can be supplied already assembled in a plastic box. A bicolour led returns information about the operating status of the device: in case of critical conditions (open filament, lamp absence) the shutdown of the power supply is forced.
