Aircraft ignition harness

PBS single-channel ignition is designed to generate voltage impulses for a spark plug, in the spark gap of which the jumping spark ignites the fuel-air mixture in the APU turbine combustion chamber or jet engine. Service life: 8 years or 3,000 starts with starts lasting 30 seconds Expected technology life cycle: 25 years or 9,000 starts with starts lasting 30 seconds The ignition device consists of a free oscillation convertor that charges the capacitor. When the internal spark gap voltage is reached, the energy accumulated in the capacitor is discharged in the spark plug. The discharge frequency depends on the supply voltage; at 14 V it is a minimum of 3 Hz, while at 30 V the minimum value is 7 Hz. Rated voltage - 28 V DC Nominal current consumption - 0,6 J Discharge frequency at 14V DC - 3 Hz ÷ 6 Hz Discharge frequency at 30V DC - 4 Hz ÷ 7 Hz Operating temperature - -55 ÷ 100°C Weight - 0,55 kg Type of operation - intermittent (with the option of permanent operation)
