Frequently Asked Questions

What is a low voltage transformer?

Every landscape lighting system is built around a low-voltage transformer. It changes the current at 120 volts into a low voltage current (between 12-15 VAC). How effectively the transformer controls the voltage output and how much energy is used during the process depends on how efficient this conversion is. The highest-performing and most energy-efficient multi-tap low voltage transformers available are called VOLT® transformers. These transformers provide a very stable source of current with very little energy usage because they have high-quality toroidal cores, sturdy wiring, and reliable internal components.

What are the different types of low voltage transformers?
Magnetic transformers

By using two coils, magnetic transformers can lower the voltage from 120 volts to 12 volts. The line voltage is carried by the primary coil (108V to 132V). Current is produced in the secondary coil by the first coil’s electrical current, which also induces a magnetic field. The secondary coil generates a current with 1/10th the voltage since it has 1/10th as many windings. Transformers for magnetic landscape lighting comes in two different varieties. These depend on the kind of core:

  • Laminated/Stacked cores have a Copper wire that is used to wound sheets, which are then layered or laminated to create a core. This is the most typical and affordable process for making a core. Compared to toroidal cores, these are less efficient, run hotter, and make more noise.
  • Toroidal cores are made out of a single, solid donut-shaped component, and the windings are wrapped both inside and outside of the donut’s hole. Toroidal cores are more expensive to produce but are more effective, buzz-free, and operate cooler. Toroidal cores work well in lighting systems with moderately high loads, as those with ten or more fixtures. In comparison to EI laminated versions, VOLT® toroidal cores are more energy-efficient, quieter, and cooler. This is crucial for transformers with higher capacities.
Electronic transformers

They do this by first raising the current’s frequency from 60 Hz to as high as 20,000 Hz, which is how they change the 120-volt current to 12 volts. The smaller, lighter, and more affordable transformer can be made possible by the smaller core that can be used at a higher frequency. The biggest drawbacks are that (1) a 12-volt electronic transformer must be placed within about 10 feet of the fixture, (2) their high-frequency current might not be compatible with LED circuits, and (3) these currents also suffer from significant voltage loss in comparison to magnetic types, (4) an electronic transformer is prone to overheat and premature failure.

How many lights can you put on a low voltage transformer?

Your overall lighting wattage and the maximum transformer draw will determine this. We advise staying under 80% of the transformer’s capacity.

Will The Low Voltage Be Fainter Than Normal Voltage?

Actually, the low voltage transformer will provide light with a similar brightness to standard voltage.

This is mostly because voltage fluctuations have no effect on lighting. The illuminating luminance of the bulb is determined by its Wattage rating.

What Are The Benefits Of This Type Of Low Voltage Transformers?

Low voltage transformers come in a wide range of sizes, therefore it is important to know what will fit comfortably. If you’re searching for a business that can offer reliable help. You won’t be penalized if you choose not to utilize one.

Conclusion

You’ve come to the right place if you’ve never bought a low-voltage transformer before and are unfamiliar with them. Customers frequently struggle to decide which choice is best for them since they are torn between a few alternative options.

We’ve provided the top outdoor transformers on the market today to help you with this chore. For you to purchase the device right away, we have also included all of the relevant information with these selections.
