Extra Low Voltage (ELV) refers to electrical systems that operate at a voltage lower than 50 volts AC or 120 volts DC. These systems are typically used in residential, commercial, and industrial settings for various applications.

Extra Low Voltage systems play a crucial role in modern buildings and facilities, providing enhanced safety, efficiency, and flexibility. By understanding the principles of ELV technology and its applications, you can make informed decisions about incorporating ELV systems into your projects.
