HOW DO I TELL MAGNETIC AND ELECTRIC LOW-VOLTAGE TRANSFORMERS APART?
Transformers may have magnetic (core and coil, toroidal) or electronic (solid-state) clearly indicated on the product. However this is not a required marking and will not be found on all products. The best way to determine transformer type is to contact the manufacturer. A hint of the transformer construction can often be found in the transformer’s weight Magnetic (core and coil, toroidal) transformers are often heavy for their size. Electronic (solid-state) transformers tend to be smaller and are often light for their size. See Application Note 19 at www.lutron.com/applicationnotes.
