Anstoss DCZ 2/12 15Hz 07000408 ignition transformer

This is the Anstoss DCZ 2/12 15Hz ignition transformer, catalogue article 155.820.037, with manufacturer codes 07000408 and 155.820.037. It belongs to the category of ignition transformers. An ignition transformer of this type steps the primary supply voltage up to the level required to generate a spark across the ignition electrode gap. It is energised only during the ignition period, under command from the burner control. Such transformers are selected on several parameters: the secondary voltage and current needed to ensure a reliable spark under the combustion chamber conditions, the primary voltage (230 V is common, but 110 V and 24 V are also available), the duty cycle, as well as the mounting arrangement and terminal pattern. The connector for the high-voltage cable often follows a specific standard pattern, so when replacing an ignition transformer it is essential to verify that the cable connector matches. The ignition cable itself is silicone-insulated to withstand both high voltage and heat from the burner. A hardened or cracked cable can leak the spark to earth, which may appear as a faulty transformer. Before replacing a suspected transformer, check the cable and the electrode gap and condition.
