1000 Watt AC/DC Power Converter, 6U VPX

The VPX56H-6 is NAI's latest high power, 1000 Watt AC/DC Converter which accepts either a 3Ø 115 VAC L-N inputs or a +270 VDC input. It plugs directly into a standard 6U VPX 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; supports all VITA standard I/O, signals, and features; and conforms to the VITA 62 mechanical and electrical requirements for modular power supplies.

The VPX56H-6 power converter is conduction-cooled through the card edge/wedgelock. It accepts 3Ø AC or +270 VDC input and provides five outputs and I/O at up to 1,000 Watts and supports a variety of standard features, including continuous Background Built-In-Test (BIT); remote error sensing; and protection against transients, overvoltage, overcurrent, and short circuits. With its intelligent design, the VPX56H-6 also has the flexibility to address special needs. Current share is standard on main outputs and optional on the +3.3 VDC_Aux output. An optional Holdup Capacitor charging circuit is available.

This COTS converter is designed specifically with NAVMAT component derating to meet the many harsh environmental requirements of rugged Mil-Aero and industrial applications.
