Anstoss Ignition transformer UBZ 2 (12) 07000578

The Anstoss UBZ 2 (12) 07000578 is an ignition transformer designed for gas and liquid fuel burner systems. It operates at a supply voltage of 12 V with a power consumption of 1.5 W. The transformer can withstand ambient temperatures up to 120 °C and has a voltage tolerance of -20% / -30%. Its application range is 14–248 °F. This component is used as a spare part for repair and maintenance of burner and boiler equipment.

When selecting a replacement ignition transformer of this type, key parameters to match include secondary voltage and current, primary voltage (common values are 230 V, 110 V, and 24 V), duty cycle, mounting arrangement, terminal type, and cable connector pattern. Always verify that the replacement unit matches the original part's duty cycle, primary voltage, secondary ratings, and mounting footprint before installation.

Ignition transformers of this kind can fail due to hardened or cracked ignition cables, which may leak the spark to ground and mimic a faulty transformer. Other failure modes include internal short circuits or open windings, leading to no spark or weak spark during ignition. Symptoms on the equipment include failure to ignite, intermittent ignition, or burner lockout after repeated ignition attempts. Check the ignition cables for damage and measure the transformer's output voltage to diagnose issues.
