PowerCoil – Cable control system for the 90SX240 bridge mount


Benefits of the Hobart Power Coil

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

Increased Safety

A 400Hz ground power cable is heavy and cumbersome. When left laying on the ground, you increase cable wear and also introduce a trip and fall hazard for your personnel. The Hobart PowerCoil is a compact system that is paired with the new compact PoWerMaster 2400 bridge mount system. It provides operation controls on the aircraft connector for cable in/out and power on/off. The cable in/out feature will help to extend cable life, reduce operator fatigue and increase ramp safety.

Hobart PoWerMaster ADV 180KVA Ground Power Units on Pad 4

On April 16, 2014, MCP completed the commissioning of ten new Hobart Ground Power Units at Airborne Command Control & Logistics Wing, Point Mugu Naval Air Station. The purpose of this project was to replace the existing 400hz power converters on the ramp with the latest in current technology. This last installation completes the population of the entire Flight Line Electrical Distribution System (FLEDS) with state-of-the art Hobart frequency converters.
Seven new converters were installed on the ramp and three were installed in the hangar completing a 6 year long project that was originally spearheaded by Ms. Stephanie Tagliaferri of Naval Industrial Services Support. These units will provide energy efficient, high quality power to E-2C and E-2D Hawkeye Aircraft, including other military and commercial aircraft with 400hz power requirements.

Among the many new benefits of this installation:

Higher energy efficiency and reduced greenhouse emissions – Hobart solid state frequency converters convert 60Hz “Shore Power” to 400Hz aircraft power by using sophisticated solid state electronics, rather than older rotary motor generators or diesel gensets. And since there is no diesel engine involved, there are no greenhouse emissions or particulates to contaminate the air. And with the high energy efficiency of these power units, energy costs are reduced significantly. Noise levels are reduced significantly as well.

New Safety Features – These new units also incorporate a new second generation military cable interlock system which senses the power cable attachment to the aircraft. If the power cable is not properly inserted into the aircraft power receptacle, the Hobart unit will not deliver power. And, if a power cord is removed while the aircraft is energized, the unit de-energizes automatically and the cable is “dead” even before the plug is pulled completely out of the aircraft. This eliminates any shock hazard to the ramp operator. Therefore, the interlock circuitry prevents “hot“ power conductors to be exposed near hands, aircraft, fuel vapors or GSE.

One Man Operation – Now, the operator can insert the power cables into the aircraft and merely press the “on” button at the Hobart control panel. No longer are two operators required to energize the aircraft, nor will there be time lost through miscommunications between GSE personnel.

Project Installation:

After the converters were installed by the local electrical contractor, MCP arrived to complete installation of the new cable interlock kits, tested each converter and conducted training classes.

Calibration and Load Testing

Testing – MCP used portable load banks to fully test each power unit prior to actual aircraft use. Doing so ensures that we have the best power quality at each and every aircraft location. Each converter and cable were calibrated for proper voltage under full operating load and also tested for proper safety interlock operation.


Training: “Just plug in the cables, press the ‘On’ button!”

Training – MCP Personnel conducted three training sessions on April 16, emphasizing the ease of use and safety factors of these new systems.

The incredible teamwork between MCP, Pueblo Construction, Tony Carlos Construction and Naval Industrial Services Support helped make the project a reality, with few glitches and quick installation times.

With the addition of these new Hobart GPU’s, several goals were accomplished:

  • Operator Safety
  • Smaller Footprint
  • Zero Air and Noise pollution
  • Lower Energy Costs

Future Plans – There are also plans to retrofit the older Hobart units installed several years ago with the new cabling interlock system, providing a consistent and safe operational method for the operators on the ramp.

The NEW 2300 Series Solid-State Frequency Converters

The New 2300 series frequency converter packs a ton of great features into the smallest package ever!

2300-vertThe standard 2300 configured with an output of 90 kVA weighs only 728 lbs and measures 22″L x 25″W x 46″H. This super compact frequency converter can be mounted horizontally or vertically to be stationary, bridge or trailer mounted. Adding a 28.5V D.C. output only increases the height of the machine by 13″ and 220 lbs. 12-pulse input rectification is also standard on all 2300 series machines.

The updated control interface on the 2300 series provides intuitive operation of the frequency converter. All of the user information is available via the digital display and can be navigated with a push-button control screen. Simple on/off buttons make the machine easy to operate and the digital read-out shows you exactly how the machine is performing.

Get the most for your energy dollar

The 2300 series is the most efficient frequency converter produced by Hobart Ground Power. 60 and 90kVA machines have an overall efficiency of 0.94 and the 30 and 45kVA machines have a efficiency of 0.93. These machines provide a 1.0 Power Factor support for B787 and A380 aircraft and can automatically calibrate its LDC settings using the optional “Auto Calibration Plug.”

Modular Design and Highly Configurable

The 2300 series frequency converter can be configured to fit any application. Vertical, horizontal, loading bridge and trailer mount configurations allow you to put the power where you need it. The compact size and light weight increase the mounting configurations more than any other equipment on the market.
Below are some of the options that are available on the 2300 series:

  • Dual 400Hz A.C. Outputs
  • 28.5V D.C. as a 2nd Output
  • Standard Mounting Kits for Passenger Loading Bridge and Trailer
