Read MoreThe Cincon CQB75W-CM/DIN Series is a compact and reliable 75 W isolated DC/DC converter designed for regulated DC power delivery in demanding industrial and system-level applications. Built in an industry-standard quarter-brick package with integrated baseplate, the CQB75W series delivers robust electrical and thermal performance under continuous operation.
Supporting a 4:1 wide DC input range, the CQB75W series accommodates fluctuating supply voltages while providing fully regulated single-output DC power across multiple output voltage options. With efficiencies of up to 87%, the converters minimise power loss and thermal stress, making them well suited for dense system designs.
The CQB75W range includes comprehensive protection features such as continuous short-circuit protection, over-voltage protection, remote on/off control, and thermal shutdown, ensuring dependable operation in harsh environments. High isolation ratings and compliance with international safety standards make this series suitable for professional power conversion applications.
Available in both chassis-mount (CM) and DIN-rail mount (DIN) variants, the CQB75W series offers installation flexibility for panel-mounted equipment and control cabinet systems.
