Rugged MIL-COTS power supply offers scalable power in small package

The VME550 Series from Aegis Power Systems Inc, a Vicor Custom Design Center, comprises rugged, reliable power supplies for aerospace, defense, industrial, and telecom applications. The VME550 operates from 28 VDC and offers scalable power in a smaller size and lighter weight than traditional DC power supplies. It is available as a 6U x 4hp single-slot conduction-cooled power card and also as a 6U x 8hp dual-slot air-cooled power card. The VME550 products feature 18-36 VDC input with capability of one to six DC outputs (one of which can be negative). The standard product, the VME550-001, offers four DC outputs (3.3 V up to 224 W, 5 V up to 224 W, and +/- 12 V up to 112 W each) with a combined total output power capability of 550 W and efficiency greater than 86%.

The VME550 Series utilizes Vicor V.I Chip power conversion technology and incorporates the new Vicor M-FIAM7B front end module to provide a scalable, flexible, open-ended bus structure capable of full 550 W output from -40[o]C to 85[o]C base plate temperature.

Designed as plug-in replacements for the VME450 Series, the new power supplies offer a number of key enhancements:

• MIL-STD-810F for shock and vibration
• MIL-STD-461E for electromagnetic interference
• MIL-STD-704A/F and MIL-STD-1275D for transient protection
• EU compliant
• CE marked to the Low Voltage Directive 2006/95/EC

In addition, design improves usability with keyed connector options that allow for the installation of multiple supplies in one chassis and dual-inhibit controls for configurable output inhibit control.
