VPX55HS

750-Watt (28VDC input) DC/DC Converter, SOSA™ Aligned, 3U VPX

The VPX55HS-31 is one of NAI's latest +28 VDC Input, VPX DC/DC Converters. The VPX55HS was developed in alignment with the SOSA™ Technical Standard and is capable of handling up to 750 Watts of output power. It plugs directly into a standard 3U VPX, conduction cooled chassis with a VITA 62, 1.0” power supply slot. This off-the-shelf solution for VITA 46.0 and VITA 65 systems is compatible with VPX specifications and supports all VITA standard I/O, signals and features. It conforms to the VITA 62 mechanical and electrical requirements for modular power supplies.

The VPX55HS-31 supply is conduction-cooled through the card edge/wedgelock. It accepts +28 VDC input voltage and provides up to six outputs per VITA 62 at up to 750 Watts with an option for the SOSATM (+12 Volt Only) configuration.  It supports a variety of standard features including continuous Background Built-In-Test (BIT), I2C communication, remote error sensing, current share and protection against transients, overvoltage, overcurrent, over-temperature and short-circuits. With its intelligent design, the VPX55HS-31 also has the flexibility to address special needs.
