Read MoreThe Cincon CQB150W-110S CMFC(D) Series is a high-performance 150W isolated DC/DC converter designed for demanding DC power systems operating from wide-range 110Vdc battery buses. With a 4:1 input voltage range (43–160Vdc), this series delivers stable, regulated DC output across varying supply conditions.
Featuring high efficiency up to 91%, reinforced 3000Vdc isolation, and comprehensive protection functions, the CQB150W-110S series is well suited to mission-critical applications where reliability, safety, and long service life are essential. The chassis-mount design with baseplate cooling supports operation in harsh thermal environments, while compliance with EN 50155, EN 45545-2, and IEC/EN/UL safety standards makes it suitable for rail and industrial power systems.
Multiple single-output voltage options are available, allowing system designers to select the optimal configuration for control, communications, and auxiliary power loads.
