VHK

CUI Europe has introduced a new line of rugged DC/DC converters that feature an ultrawide 4:1 input and provide 50-200W of output power. These chassis-mount units are enclosed in a 4.25-inch x 4.00-inch x 1.50-inch aluminum case and include a built-in heat sink for improved thermal performance. The VHK series is perfectly suited for various communications and industrial applications where rugged design is required.

Users can select from an input voltage range of 9-36Vdc or 18-72Vdc and output voltages of 3.3-, 5-, 12-, 15-, 24- or 48Vdc. The standard operating temperature range is -40C to 85C, with the 50W model operating up to 60C under convection-cooled conditions. Safety features of the VHK series include over current, over temperature, input transient and short circuit protections.

Additional features include high efficiency, fast transient response, remote sense and remote on/off control. Most models are available immediately through Digi-Key with prices starting at $125 per unit.
