Excelsys Xgen XF Series AC-DC Mil-COTS/Harsh Environment Power Supply




CUSTOMIZABLE POWER FOR HARSH ENVIRONMENTS AND MIL-COTS APPLICATIONS

The Excelsys XF series AC-DC Mil-COTS/harsh environment power supply is a highly-flexible field-configurable power supply ultimately delivering customized power in virtually minutes. Its modular architecture allows for fast custom configurations by the user in the field or on the bench during development and qualification. The Excelsys XF series offers power outputs of 400W ( XFA series), 700W (XFB series) and 1000W (XFC series), with up to 12 isolated outputs. Outputs of 1 VDC through 58 VDC and series and parallel combinations of modules are possible. The XF series is shock and vibration resistant to MIL-STD-810G; excellent for harsh conditions and mobile applications. All configurations carry full safety agency approvals, including UL60950 and EN60950 and are fully characterized for EMC according to MIL-STD-461F. EMC Characterization, Shock and Vibration and Thermal Stress reports are available upon request. For full specifications, please see below.
