The VPX55H-3 is NAI’s latest high power 500 Watt DC/DC converter that plugs directly into a standard 3U VPX chassis with a VITA 62 0.8” power supply slot. This off-the-shelf solution for VITA 46.0 and VITA 65 systems is compatible with VPX specifications; supports all VITA standard I/O, signals, and features; and conforms to the VITA 62 mechanical and electrical requirements for modular power supplies.
The VPX55H-3 switching power supply is conduction-cooled through the card edge/wedgelock. It accepts +28 VDC input voltage and provides six outputs at up to 500 Watts.
The VPX55-3 can be used either as a single-stage module or a back-end module in a multiple power supply configuration. It supports a variety of standard features, including continuous Background Built-in-Test (BIT); remote error sensing; and protection against transients, over-voltage, over-current, and short-circuits. With its intelligent design, the VPX55H-3 also has the flexibility to address special needs. Optional current share available.
This COTS converter is designed specifically with NAVMAT component derating to meet the many harsh environmental requirements of rugged Mil-Aero and and industrial applications.
