Frequently Asked Questions (FAQs)

1. What are low voltage transformers used for?

Low voltage transformers are commonly used for low voltage lighting, which typically only uses 12 or 24 volts. There are also many low voltage transformers to meet the needs of defense, manufacturing, medical care and research industries.

2. What is a low power transformer?

Figure 1: Low voltage transformer. A transformer is an electrical device designed to convert alternating current from one voltage to another. A low voltage transformer converts the main power supply voltage to a lower voltage, usually 12-15 volts.

3. Can I plug a low voltage transformer into an extension cord?

An extension cord should never be used between the transformer and the electrical outlet. Plug the transformer directly into the power outlet. Low voltage outdoor lighting is not hard to install or maintain.

4. How many watts do I need for low voltage transformer?

Again, if you want to connect twenty landscape lights to a low volt transformer, and the lights are pulling 4W / 7VA / 35 Watts of halogen power draw on the system, you would need a 300 watt transformer.
