Expanding their DIN rail DC/DC product line, CUI has introduced 90 models in the 50-600W range. The VHK DIN and VFK DIN isolated DC/DC converters can operate at higher temperatures (up to +85°C) with a minimal amount of air flow.

Featuring an ultra-wide 4:1 input, the converters have been designed for applications where the convenience of DIN rail mounting is required, such as industrial equipment, mobile equipment and telecomms base stations. They operate over a temperature range from -40 to +85°C, with the 50W model operating at up to 60°C with convection-cooling. The 600W VFK600-DIN series comes with load share capability for applications that require power above 600W.

The 50-400W models operate from input voltages of 9-36VDC or 18-75VDC; while the 600W models operate from input voltages of 18-36VDC or 36-75VDC. Output voltages of 3.3, 5, 12, 15, 24, 28, 32, or 48VDC are available. Packaged in a rugged aluminium case, the 50-200W VHK DIN family measures 107.5x101.8x52.6mm (4.23x4.01x2.07") and the 400-600W VFK DIN family measures 199.0x127.0x53.6mm (7.83x5.00x2.11").

The isolated DC/DC converters feature over current, over temperature, input transient and short circuit protections, as well as output trim, remote sense and remote on/off control.

The VHK DIN and VFK DIN families are available now priced from $143 each in 50 unit quantities.
