110 V DC/DC converters likely to move

11 July 2007 Power Electronics / Power Management

Targeting transportation applications, Vicor has developed a 24-model series of Maxi, Mini and Micro DC-DC converters for 110 V d.c. input. This new series includes eight standard output voltages of 3,3, 5, 12, 15, 24, 28, 36 and 48 V in combination with three different package sizes (quarter brick, half brick, full brick) with output power ranging from 50 W up to 400 W, depending on the model.

The new products feature a wide input voltage range (66-154 V continuous operation) in accordance with EN50155, encapsulated circuitry for shock and vibration and extended temperature ranges. This makes them ideal for railway and transportation system applications, including communication systems, information displays, lighting, control systems, ticket machines, passenger entertainment, public address systems and power generation systems.

Efficiencies range up to 90% for the higher output voltages. The models are available in five different environmental grades, with six different pin options and three baseplate options. They can also be configured in any combination using Vicor PowerBench, a patented intelligent design system that allows a customer to configure a vast array of custom module designs online, and verify them in realtime, at www.vicorpower.com.

The modules, which are optionally available in RoHS compliant models, measure for Maxis 117 x 55,9 x 12,7 mm; for Minis 57,9 x 55,9 x 12,7 mm; and for Micros 57,9 x 36,8 x 12,7 mm in size with a height above board of 10,9 mm.
