DC/DC converters for halogen lamps CH series Our CH series converters are used for the power supply of halogen lamps. Besides an important robustness and resistance to vibrations, they are protected against short-circuits and overloads. Thanks to an appropriate soft-start, the halogen lamps have no luminous over-intensity when starting, even when only a part of halogen lamps is under voltage. The output voltage regulation is particularly accurate, even at high temperature. The CH series converters have an excellent efficiency. Our CH series converters are used in railways, metros and tramways. General information : Technical brochure
