WIENER VPX power supplies are designed as conduction-cooled, commercial off-the-shelf (COTS) single-stage converters according to the ANSI/VITA 62.0 specification. Built for seamless integration into standard VPX chassis, they conform to the mechanical envelope defined by VITA 46.0. Advanced switching power technology ensures excellent efficiency and a broad input voltage range. The VPX340 and VPX315 series are fully tested to comply with MIL-STD standards for performance in demanding environments. Intelligent onboard monitoring and control is available via I²C and USB interfaces.
