Industrial DDI48 12108 Isolated DC-DC Converter

Alfatrionix DDi48-12-108 is an isolated DC-DC converter in the DD/ DDi family that converts a 12–48 V DC input to a regulated 12 V output while delivering up to 9–10 A of continuous current (approximately 108 W). The unit's isolation between input and output helps protect downstream electronics from transients and ground loops, a key feature of Alfatrionix's isolated lineup designed for harsh environments. This variant sits in the 48 V–12 V segment of the DDi line, with power options spanning 36 W, 72 W, and 108 W ratings, making it suitable for industrial control panels, automotive and marine applications, and equipment that must run from fluctuating vehicle or plant power. The 12–48 V input range accommodates common vehicle and industrial power buses, and the converter is built to handle engine-start surges and wide operating temperatures typical of rugged deployments. With its compact enclosure and fixed 12 V output, it provides a reliable rail for sensors, controllers, and communication gear in mobile or fixed installations. For buyers choosing Alfatrionix’s DD/ DDi lineup, this 108 W model offers the middle-to-high end of the 12 V output options, balancing current headroom with space and thermal performance for demanding installations.
