Overview

The Expbus II is a lifesaver when wiring up your homebuilt project. The EXPBUS II is a complete electrical system on a special high current, printed circuit board.
14V DC systems (not recommended for 28V aircraft)

KITPLANE ELECTRICAL SYSTEM ON A PC BOARD:

  • EXPBUS II--Second generation design
  • Simplifies and organizes wiring
  • Saves time, panel space, weight, and money
  • Solid state "fuses" eliminate breakers
  • Avionics master switch/starter cutout
  • "Soft Start" extends landing light life
  • Overvoltage protection
  • Clearance delivery input for NavCom
  • Dual bus option for backup battery

The current ratings are based on "recommended" operating current. Traditional fuses and circuit breakers are rated in terms of "maximum" operating current. A 9 amp polyfuse circuit is roughly comparable to a 14 amp fuse or breaker. The above fuse sizes are a good match for most sport aircraft, your project will probably work well with this configuration. For a small additional charge, we can configure your board with any size (1 to 11 amps) breakers in any position.
Size: 7.8" long by 3" deep by 1.9" tall. Weight 0.8 lbs.
