PRODUCT OF THE WEEK: AirBorn Power Blade VPX power supply

March 18, 2024

This week’s product, AirBorn’s Power Blade VPX power supply, is a 6U Power Blade 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 Power Blade 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, Power Blade’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.


The Power Blade 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 Power Blade 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. Power Blades may be paralleled for higher power requirements.

Reduced SWaP-C

The Power Blade 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
