72 V DC-DC converters target transportation

17 September 2008 Power Electronics / Power Management

Vicor has added a new 72 V input series for the Maxi, Mini and Micro family of DC-DC converters.

This new series greatly expands Vicor’s product offering for the railway and transportation segment, which values product robustness and reliability. It consists of 27 new models including nine standard output voltages (3,3, 5, 8, 12, 15, 24, 28, 36, and 48V) in combination with three package sizes (quarter, half, and full brick) with output power ranging from 75 W up to 400 W depending on the model.

These models meet the operating voltage requirements for EN50155, the key standard for railway applications, as well as EN50155 requirements for shock, vibration and temperature. The product platform simplifies thermal management and mounting for designers with a proven baseplate design, and the encapsulated circuitry provides robustness for shock, vibration and humidity often found in these applications. They 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 tools that allow a customer to configure an infinite array of custom module designs online, and verify them in realtime.

The modules, which are optionally available in RoHS compliant models, have the following dimensions: the Maxi is 117 x 56 x 12,7 mm; the Mini is 57,9 x 55,9 x 12,7 mm, and the Micro is 57,9 x 36,8 x 12,7 mm.
