Two-channel Ignition Device

Product catalog summary

Purpose of the Product: The P/N 86500.03 ignition device is designed to generate voltage impulses for two spark plugs, igniting a fuel-air mixture in a turbojet engine's combustion chamber.

Technical Specifications:

Nominal Voltage: 28 V DC
Nominal Current Consumption: < 3 A
Operating Voltage: 14 V DC to 30 V DC
Output Voltage: 2.5 to 3 kV
Supplied Energy: > 0.6 J/channel
Discharge Frequency: 3 Hz to 6 Hz at 14V DC, 4 Hz to 7 Hz at 30V DC
Operating Temperature: -55°C to 100°C
Weight: 1.1 kg
Operational Mode: Intermittent, also suitable for continuous operation

Operating Conditions: The device meets various environmental conditions based on RTCA/DO-160E and ISO 2678 standards, including temperature, humidity, shock, vibration, and more.

Technical Description:

The device contains electronic circuits for converters on printed circuit boards, housed in a sealed metal box with connectors for supply voltage and cables.
It features two separate channels, each with a converter charging a capacitor, discharging energy to the spark plug when a specific voltage is reached.

Instructions for Use:

Ensure correct polarity and reliable electrical connection during installation.
Recommended intermittent mode: 30 seconds operation + 2.5 minutes rest, but continuous use is possible.

Maintenance Instructions: No special maintenance is required; send to manufacturer for overhaul after 8 years or 3,000 starts.

Service Life and Guarantees:

Service Life: 25 years or 9,000 starts, whichever comes first.
Guarantee: 12 months or 500 starts, provided installation and operating conditions are met.

Repair Instructions: The device cannot be repaired or disassembled.

Ordering Products: Orders must specify the P/N, quantity, conservation method, and document language (English).

Delivery Includes: One ignition device, no spare parts or tools, and accompanying documentation (Certificate of Quality and Completeness).

Two-channel Ignition Device Instructions for use For installation dimensions, see the Installation Dimensions section. When installing the ignition device, it is necessary to ensure correct polarity of the ignition wiring (see Installation Dimensions). When installing the ignition device, at least one fastening point must be reliably (electrically) connected to the frame of the engine. The recommended intermittent mode consists of 30 seconds of operation + 2.5 minutes of rest. However the device can be used continuously if needed (e.g. when flying in rain). No setting has to be made and no special...
