CUI, Inc. (Tualatin, OR) announced the expansion of their DIN rail dc-dc product line with the addition of over 90 new high wattage models ranging from 50~600 W. 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. With efficiencies as high as 92% 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. Other features include:
• Input voltages of 9~36 Vdc or 18~75 Vdc for 50~400 W models and 18~36 Vdc or 36~75 Vdc for 600 W models.
• Output voltages of 3.3, 5, 12, 15, 24, 28, 32, or 48 Vdc.
• Standard operating temperature range of -40~85°C, with the 50 W model operating up to 60°C under convection-cooled conditions.
