Anstoss Ignition transformer ZAG 2 07000088/03

The Anstoss ZAG 2 ignition transformer (SKU 07000088/03) is a Type 1 device designed for burner equipment in heating systems. It operates on a supply voltage of 220–240 V at 50–60 Hz, with a power consumption of 2.5 W. The transformer generates a high-voltage pulse to ignite the fuel mixture in gas and oil burners, ensuring stable spark generation. Its compact design facilitates easy installation in automatic ignition systems. The maximum ambient temperature is 85 °C, and it features silicone-insulated ignition cables.

When selecting a replacement ignition transformer of this kind, verify that the primary voltage, frequency, and power rating match the burner's control circuit. The mounting arrangement and terminal type must be compatible with the existing installation, and the high-voltage cable connector pattern should align. Measure the physical dimensions and compare the duty cycle to ensure suitability. Inspect the ignition cable for hardening or cracks, as damaged silicone insulation can cause spark leakage.

Typical failures of ignition transformers include internal short circuits or open windings, leading to no spark or weak spark at the electrode. The burner may fail to ignite or lock out after repeated ignition attempts. Check the transformer's primary voltage during the ignition phase, inspect the high-voltage cable for insulation breakdown, and verify the electrode gap and ground connection to the chassis.
