FoxCart 1600 Aircraft Ground Power Unit – 50/60 Hz, 800A Continuous, 1,600A Peak Start

The FoxCart 1600 Ground Power Unit (GPU) is designed to provide smooth, high-current DC power to aircraft during engine starts or ground maintenance. When used as an external DC source, the FoxCart GPU eliminates or minimizes excessive current drain from the aircraft's battery and battery-relay contacts. This low-profile unit requires minimum ventilation and is easily moved in a crowded hangar by one person.

The FoxCart 1600 ground power unit comes in both 50 Hz and 60 Hz power options, both of which need 3-phase power from your hangar or local facility.

FoxCart Ground Power Unit Overview

The FoxCart is enclosed in an all-steel chassis frame with a three-piece steel box siding. There are handles at each end to move it. The power cables can be wrapped around the handles or coiled on top for storage. The wheels can be locked in place to prevent movement. Both power cables are clamped internally to the frame for strain relief. The controls marked "optional" are not included in the standard FoxCart unless ordered by the customer.

Warranty

FoxCart and Unitron aircraft ground power units warrant each new FoxCart Mark II Series to be free of defects in material and workmanship, under normal use and service for one year from the date of shipment. Subject to change.

Dimensions (Including Handles)

• Standard Model FoxCart: 50.5" L x 30" W x 31.5". H
• FoxCart with Terrain Wheels: 50.5" L x 30" W x 38" H

Available Options

Please request options at the time of the quote request.

• Soft Start
  • Limits Starting Current to 1100 AMPS to protect engine starters and starter drives that require this feature
  • Softstart provides current limiting during engine starts to prevent over-torquing starter motors and starter drive mechanisms during starts. Use this option only if your aircraft requires it. During a Softstart, the Foxcart produces about 20% or more of the current needed for a start and the Aircraft batteries supply the remaining current. If the Aircraft design maintains the ship's batteries online, the FOXCART will supply all the power. After the start, if the FOXCART is left online long enough, it will recharge the Aircraft batteries.
• Terrain Wheels
• 100' AC Input Cable
• Water Proofing - See You Ask. We Help. Section Below for More Info on this Option

18" Riser Option

Please request this option at the time of the quote.

What is the 18" Riser Kit Option?
The new 18" riser kit is to be fully compliant with the safety regulations of the hangar environment. This well-known "18-inch rule" requires there be no electrical connection allowed within the 18-inch area above the hangar floor known as a Class 1, Division 2 area. This area is considered hazardous because fumes from spilled jet fuel may not yet have dispersed sufficiently to avoid ignition was an arch to occur; in this context, from a loose electrical connection within a mobile power unit (GPU or cart). Reference Article 513 of the NEC and EN 60079-10 of the European Standard for a more thorough explanation of this ruling.
