Overview

The Champion Aerospace Ignition Exciter Assembly, Model CH92133 is eligible by FAA-PMA for use on the Rolls-Royce Model 250 Series I, II, III & IV turbine engines as approved for replacement of the following exciter models:

Rolls-Royce
  • PN 6899093
  • PN 6895573
Unison
  • PN 10-614950-1
  • PN 10-387150-1
  • PN 49522

Features

  • The exciter consists entirely of solid state circuitry with no “wear out”
  • characteristics to ensure consistent performance and long life
  • The exciter does not contain radioactive materials as these materials are not
  • necessary for operational stability
  • The exciter presents the same footprint, form and weight as the OEM part so
  • that installation and the weight/balance of the airframe is not affected

Specifications

  • Input Power:
    • 14-30 VDC
    • 1.1A typical, 1.5A (max.)
      • Operational duty cycle: Continuous @ 185°F (85°C)
      • Operational Temp. Range: -54 to +121°C
      • Spark Rate:
        • 5 to 15 sparks/second
        • (Input voltage dependent)
      • Output voltage: 7kV minimum (8kV typical)
      • Output waveform: Unipolar, 40µs spark duration
      • Stored energy: 1.4 joules nominal

Benefits

  • Vibration tested to 35g for 9 hours, 3 axis (Sinusoidal)
  • Shock tested to 30g, 3 axis (Saw-tooth impulse)
  • High temperature endurance tested at 250°F (121°C) 300 hours
