The biggest downsides are (1) their high-frequency current may not be compatible with LED circuits, (2) these currents also suffer from extensive voltage loss compared to magnetic types, (3) a 12-volt electronic transformer must be positioned within about 10 feet of the fixture and (4) electronic transformers are subject to overheating and premature failure. The increased frequency allows the use of a miniature core enabling the transformer to be very small, light and inexpensive. This is especially important for larger capacity transformers.Įlectronic transformers convert the 120-volt current to 12 volts by first increasing the frequency of the current from 60 Hz to as high as 20,000 Hz. VOLT® toroidal cores are more energy-efficient, quieter and cooler than EI laminated-types. Lighting systems with relatively high loads - such as 10 or more fixtures - benefit the most from toroidal cores. ![]() Toroidal cores are more efficient, experience less buzz and run cooler but are more expensive to make. These are one solid unit shaped like a donut and have the windings wrapped around the donut, in and out of the donut hole. These are less efficient, run hotter and are noisier than toroidal cores. This is the more common, less expensive method for manufacturing a core.
