Technical Specifications Primary input: 24 V DC nominal, 18–30 V operating; secondary output: up to 28 kV peak; spark energy: 100 mJ typical at 2 ms dwell; operating temperature: -40 °C to +130 °C; insulation class: H; enclosure rating: IP65; dwell range: 1–15 ms.
Functional Features High spark energy output; fast voltage rise time; thermally insulated winding; corrosion-resistant housing; internally suppressed EMI; short-circuit protected primary.
Application Scenarios Industrial gas engine ignition, natural gas generator sets, biogas and landfill gas engines, stationary engine ignition systems, high-altitude engine applications.
Performance Parameters Spark energy consistency: ±4%; rise time: < 8 µs; insulation withstand: 32 kV peak; primary resistance: 0.4 Ω typical.
Material Composition Epoxy-encapsulated copper winding; grain-oriented silicon steel core; high-voltage ceramic insulator; steel mounting bracket; silicone rubber boot.
Structural Characteristics Bracket-mounted coil assembly; threaded high-voltage terminal; primary blade connectors; slotted mounting holes for adjustment.
Working Principle Primary current builds magnetic flux in the coil core. When primary current is interrupted, the collapsing magnetic field induces a high-voltage pulse in the secondary winding, delivering a high-energy spark across the spark plug gap.
Installation Requirements Mount on engine bracket or cylinder head; connect primary wiring to ignition controller; attach high-tension lead to spark plug; torque mounting fasteners evenly.
