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.  |
