DC-DC converters feature integrated heat sink

CUI Inc.’s power line, V-Infinity, announces the release of a new line of rugged dc-dc converters that provide 400 W of output power. The VFK400 Series is a chassis-mount solution measuring 7.8 x 5.0 x 1.5 in. and includes an integrated heat sink for improved thermal performance. The aluminum heat sink allows the unit to operate at higher temperatures with a minimal amount of air flow.

The VFK400 Series accepts an ultra-wide 4:1 input and can support either 10 to 36 Vdc or 18 to 75 Vdc isolated input voltages. The wide input range is useful when being driven from a fluctuating device like a battery, which can see both charging and discharging conditions. The dc-dc converter is offered in three different regulated output voltage versions: 12, 24, and 48 Vdc. High efficiency, fast response, tight regulations, remote sense, and remote on/off control make these converters suitable in many industrial and communications applications.

Standard features include over-temperature, over-current, and input transient voltage protection. With an external input fuse, the converter can also protect against accidental polarity reversal.
