Information About ET401A1
The ET401A1 belongs to Honeywell’s Thermal Solutions ignition transformer line, designed to ignite gas pilots in heating and process combustion systems. It supports electrode gaps between 0.12 and 0.20 in (3–5 mm), producing a stable, high-frequency discharge with low electrical noise output. Its compact housing allows direct mounting beneath a burner control box, simplifying integration into confined spaces. The transformer’s conforming approvals, robust encapsulated design, and dependable duty cycle (33% – 60 s on / 120 s off) make it ideal for OEM and retrofit burner applications requiring precise, repeatable ignition.
Key Features:
- High Output Voltage: Generates 14.0 kV peak for reliable ignition of interrupted gas pilots and burners.
- Optimized Spark Gap: Supports electrode spacing from 0.12 to 0.20 in (3 – 5 mm) for consistent arc formation.
- Low Electromagnetic Interference: Produces minimal EMI emissions, compliant with EN 55014-2 standards, protecting sensitive control electronics.
- Compact, Easy-Mount Design: Engineered to fit directly under Honeywell burner control boxes using standard hole patterns.
- Low Inrush Current: Reduces electrical stress during startup, extending transformer and system lifespan.
- Energy Efficient: Combines low power consumption with high output energy efficiency for long-term operation.
- Manual Reset Safety Cycle: Interrupted ignition type with 33% duty cycle (60 s on / 120 s off) for safe re-ignition intervals.
- UL Recognized: Certified under UL 1012 and 506 standards for safety and performance assurance.
- Durable Construction: Encapsulated, moisture-resistant body with long-life windings suitable for continuous industrial use.
- Environmental Resilience: Operates in ambient temperatures from –15 °C to 60 °C (5 °F to 140 °F) and up to 90 % relative humidity.
The ET401A1 delivers the reliability and ignition precision required for industrial gas burners, heaters, and process combustion systems.
