Transformateur d'isolation De Dietrich S100489

The isolation transformer is an electrical component used in burners and boilers to provide galvanic isolation between the power supply and control circuits. It helps protect sensitive electronics from voltage spikes and ensures safe operation. This transformer is often used in burner control systems and is a critical part for maintaining reliable ignition and flame detection. When servicing heating equipment, replacing a faulty isolation transformer can resolve issues with burner startup or erratic behavior.
