PRODUCT OF THE WEEK: AirBorn VPX power supply

This week’s product, AirBorn’s VPX power supply, is a 6U DC-to-DC module that is VITA 62 and OpenVPX compliant and provides 2000 W+, a level nearly 2x the output of traditional 6U VPX power supplies. The device is a rugged SOSA aligned, conduction-cooled switch mode unit built for use in high-end defense and space applications like radar, C4ISR, electronic warfare, and more.

The VPX power supply has embedded intelligence that enables flexible sharing through dispatchable power that can be configured to control voltage, balance current, or temperature across multiple power supplies. Additionally, the part’s intelligence allows system designers to utilize a dual data bus communication where a system controller or chassis manager can talk to the power supply and inquire about input voltages, output cards, power temperatures, and other information from the power supply, possibly predicting failures.

Efficiency

The part has an efficiency of 95%, enabling customers to support the higher power levels required in modern defense applications without increasing the size of their power-supply units.

Each VPX power supply delivers in excess of 2000 Watts. Power dissipation of less than 128 W per board enables most existing systems to be immediately upgraded for higher power, with less loss per board. Lower losses mean lower operating temperatures and higher reliability. The parts may be paralleled for higher power requirements.

Reduced SWaP-C

The VPX power supply enables meets the military stringent requirements for reduced size, weight, power, and cost (SWaP-C) with features that include:

Fewer power supplies needed as the module provides more power
Extremely clean power reduces filtering needs
- CE101/102 compliant without external filters
- Very low ripple and noise on DC outputs over full range
Easy to install
- ANSI/VITA 62.0 compliant
- Direct replacement with no backplane change
