Low Voltage Transformer
Definition of Low Voltage Transformer
A low voltage transformer is an electrical device that converts high voltage electricity to low voltage electricity, typically from 120 volts AC down to 12 volts AC or 24 volts DC. It’s also known as a step down transformer.
Low voltage transformers are important in LED and boat lighting systems as LED lights typically operate on low voltage, and a transformer is necessary to convert the higher voltage supply to the appropriate level.
Here are the main types of low voltage transformers:
- Magnetic transformers: These are the most common type of low voltage transformers and use a magnetic field to convert the voltage in the primary winding to a lower voltage in the secondary winding.
- Electronic transformers: These smaller and lighter transformers use capacitors and semiconductors to lower voltage from the primary winding to the secondary winding. They’re also common in LEDs as they provide constant voltage and enable dimming.
- Toroidal transformers: A type of magnetic transformer that uses a toroid-shaped core. They are more efficient than other types of transformers and produce less electromagnetic interference.
- Wire-wound transformers: These transformers use a wire-wound coil to transfer energy from the primary winding to the secondary winding. They are often used for low voltage landscape lighting and underwater lighting.
