Vicor has announced the introduction of a 110 Vdc input series of 24 models of Maxi, Mini, and Micro DC-DC converters. This new series includes eight standard output voltages (3.3, 5, 12, 15, 24, 28, 36, 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 on-line, and verify them in real time, 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.
