Dc-dc converters offer 4:1 input in a rugged chassis mount package

V-Infinity, a division of CUI Inc, introduces the VHK Series of rugged dc-dc converters that feature an ultra-wide 4:1 input and provide 50~200 W of output power. These chassis-mount units are enclosed in an aluminum case measuring 4.25x4.00x1.50 inches 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 to 36 Vdc or 18 to 72 Vdc and output voltages of 3.3, 5, 12, 15, 24, or 48 Vdc. The standard operating temperature range is -40 to 85°C, with the 50 W model operating up to 60°C 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.
