DC-DC Converters for
Industrial Applications
Isolated Modules from 10~700 W

CUI’s comprehensive line of 10~700 W DC-DC converters are a rugged solution for the harsh environments that often characterize industrial use. Reliable and compact, these isolated modules have a -40°C to 85°C operating temperature range and offer an efficiency up to 92%. The 4:1 and 2:1 input range options combined with a variety of mounting packages, including board mount, chassis mount and DIN rail, provide engineers with the flexibility they need. All of CUI’s industrial DC-DC converter series come with over-current, over-temperature, over-voltage, and short-circuit protections and remote on/off control.
