DC-DC converters support 50-600W operation
CUI Inc. has extended its DIN rail DC-DC portfolio with the introduction of more than 90 high wattage models ranging from 50-600W. The VHK and VFK DIN families are high efficiency isolated DC-DC converters packaged in a rugged aluminum case that feature an ultra-wide 4:1 input, stated the company.
With efficiencies as high as 92 per cent and an integrated aluminum heat sink, the units are able to operate at higher temperatures with a minimal amount of air flow. They have been designed for applications where the convenience of DIN rail mounting is required such as industrial equipment, mobile equipment and telecom base stations.
Users can select from input voltages of 9-36VDC or 18-75VDC for 50-400W models and 18-36VDC or 36-75VDC for 600W models. Output voltages of 3.3, 5, 12, 15, 24, 28, 32 or 48VDC are available depending on the series. Standard operating temperature range is -40°C to 85°C, with the 50W model operating up to 60°C under convection-cooled conditions.
Safety features of the VHK and VFK DIN series include overcurrent, overtemperature, input transient and short circuit protections. Additional features include output trim, remote sense and remote on/off control. For applications that require power above 600W, the VFK600-DIN series comes standard with load share capability.
The VHK DIN family ranging from 50-200W measures 107.5 x 101.8 x 52.6mm while the VFK DIN family ranging from 400-600W measures 199 x 127 x 53.6mm. All electrical connections are easily accessible via screw terminals.
The VHK and VFK DIN families are available through distribution starting at $143 for 50 pieces, with production availability from 8-12 weeks.
