The Cincon CQB50W12 CMFC(D) Series is a rugged range of isolated DC/DC converters designed for railway, industrial, and infrastructure applications requiring reliable low-voltage power from wide and fluctuating DC sources. With a 12:1 ultra-wide input range (14–160 Vdc), the series is well suited for rolling stock, trackside equipment, and harsh industrial environments where supply conditions are unpredictable.

Delivering up to 50 W of regulated output power, the CQB50W12 series is available with single output options of 5 Vdc, 12 Vdc, 24 Vdc, or 48 Vdc. High efficiency (up to 89%), low no-load power consumption, and fully regulated outputs ensure stable operation for control electronics, communication modules, and auxiliary systems.

The converters feature a chassis-mount, baseplate-cooled design for fanless operation and long service life. Compliance with EN50155, EN45545-2, and IEC/EN/UL 62368-1 makes the CQB50W12 CMFC(D) Series a dependable choice for rail and other safety-critical infrastructure applications. Optional covers, heatsinks, and DIN-rail mounting accessories provide flexibility for system integration.
