The Cincon CQB150W Series is a high-performance 150W isolated DC-DC converter featuring a wide 4:1 input range, high efficiency up to 92%, and full industrial and railway compliance.

Designed in an industry-standard quarter brick package (2.28” x 1.45” x 0.5”), the CQB150W delivers regulated single outputs with robust protection including OCP, OVP, OTP and UVLO. With 2250Vdc input-to-output isolation, operation up to 3000m altitude, and compliance to EN50155 (with external circuits), this series is ideal for railway, transportation, industrial automation, and harsh-environment applications.

The series supports nominal 24V and 48V systems with output voltage options from 12V to 48V, delivering up to 12.5A output current depending on model.
