Power Coil – 90kVA Bridge Mount Unit with Cable Reel

2400-cable-reel

The Hobart Power Coil is the optimal choice for installation under a passenger boarding bridge. The revolutionary 2-in-1 solution with a 400 Hz 90 kVA ground power unit and a cable reel in one housing represents a radical improvement in the industry.

The installation and start-up of the Hobart Power Coil is very simple. You only have to mount the unit under the bridge, connect it to the utility supply and power is available at the aircraft plug. No further testing or adjustment is necessary.

Benefits of the Hobart Power Coil

  • Easy installation
  • Less stress on the passenger boarding bridge
  • Optimized for all-electric aircraft
  • Optimum voltage quality at the aircraft pluq
  • High reliability and easy maintenance
  • Quick connection
  • Powered In & Out to minimize the risk of injury to ramp personnel
