Read MoreThe Cincon CQB150W-110S Series is a high-performance 150W isolated DC-DC converter designed for demanding industrial, railway, and high-voltage DC applications. Featuring a wide 4:1 input range (43–160VDC) and delivering tightly regulated single outputs, this quarter-brick converter provides reliable and efficient power conversion in harsh environments.
With efficiency up to 92%, 3000VDC isolation, and comprehensive protection functions including OCP, OVP, OTP, and UVLO, the CQB150W-110S Series ensures safe and stable operation even in mission-critical systems. The module complies with EN 50155 (with external circuits), EN 45545-2 fire & smoke standards, and meets IEC/EN/UL 62368-1 safety requirements.
Housed in an industry-standard Quarter Brick (2.28” x 1.45” x 0.5”) package, the CQB150W-110S is ideal for railway systems, industrial automation, transportation, battery-powered equipment, and high-voltage DC bus architectures requiring robust isolated conversion.
