TRANSFORMERS by ALLANSONKnown at "iron core" transformer, it draws 120 vac into the primary coil. The steel plates of the transformer core transfer the primary coil's 60Hz magnetic field to the secondary coil. The secondary coil uses this field to produce a high output voltage of 10,000 VRMS open circuit (when there is no secondary current flowing) that has a frequency of 60Hz. Allanson transformers are designed and tested to burner manufacturers specifications and have a
