- Fits standard VPX chassis per VITA 46.0 (3U x 4HP)
- High-efficiency single-stage converter with wide input voltage range
- Flexible power distribution across VS1, VS2, and VS3 due to oversized converters
- MIL-STD 461, 704, 1275 tested; I²C and USB monitoring via onboard microcontroller
Product Information
VPX336 power supplies are conduction-cooled, commercial off-the-shelf (COTS) single-stage converters built to the ANSI/VITA 62.0 standard. Designed to fit standard VPX chassis as specified by VITA 46.0, they deliver high overall efficiency and support a wide input voltage range through advanced switching power technology. Each main converter is deliberately oversized to allow multiple configuration options – either prioritizing 12V output or distributing power more evenly across all three main output rails.
The VPX336 series is compliant with key military standards (MIL-STD-461, 704, 1275) and features an embedded microprocessor for real-time monitoring and control via I²C or USB. Mechanically, the unit measures 3U x 4HP and includes all keying, connector, and alignment elements in line with VITA 62.
