3U power supply VPX360

DC/DCmultiple-outputSMPS

Overview
The Kontron VPX360 Air-cooled is a commercial off-the-shelf VPX power supply designed to ANSI/VITA 62.0 for integration into standard VITA 46.0 VPX systems. It delivers up to 600 W in a compact 3U form factor, using next-generation power conversion for high efficiency and dense power delivery.

Product information
Separate versions support nominal 28 V DC or 48 V DC input systems, with a wide operating input range from 12 V DC to 68 V DC. The VPX360 provides multiple main and auxiliary output voltages, programmable power sequencing, comprehensive protection functions and onboard monitoring via I²C, USB-C and optional IPMI. The electronics are conformal-coated and the unit is engineered to meet VITA and MIL standards relevant to embedded and rugged platforms. Compliance testing is pending where indicated in preliminary documentation.
