For Your Information: Transformer Technology
What are Magnetic Transformers?
These transformers use two coils, a primary coil and a secondary coil, to reduce the voltage from 120 volt down to 12 volts. The primary coil carries the line voltage (108 v to 132 v). The flow of electricity through the primary coil induces a magnetic field that creates a current in the secondary coil. Since the secondary coil has 10 times fewer windings, it creates a current with 10 times lower voltage.
Two Magnetic Types. There are two types of magnetic landscape lighting transformers. These vary by the type of core:
- Laminated/stacked cores (also know as EI type). Laminated or stacked windings have sheets wrapped in copper wire that are then stacked or laminated together to make a core. This is the more common, less expensive method for manufacturing a core. These are less efficient, run hotter and are noisier than toroidal cares.
- Toroidal cores. These are one solid unit shaped like a donut and have the windings wrapped around the donut, in and out of the donut hole. Toroidal cores are more efficient, experience less buzz, and run cooler but are more expensive to make.
The choice of whether or not to use a toroidal core also depends the system load. Systems with relatively high loads - such as lighting systems with 10 or more fixtures, benefit the most from toroidal cores; smaller systems - such as those with less than 50 watts of load, are served well with EI laminated types.
What are Electronic Transformers?
This transformer type converts 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). The increased frequency allows the use of a miniature core enabling the transformer to be very small, light, and inexpensive. The biggest downside is that their high frequency current may not be compatible with LED circuits. These currents also suffer from extensive voltage loss compared to magnetic types. A 12-volt electronic transformer must be positioned within about 10 ft. of the fixture. Electronic transformers are also subject to overheating and premature failure.
