ELV System
ELV (Extra Low Voltage) System refers to a category of electrical systems that operate at voltages below 50V AC or 120V DC. These systems are commonly used in residential, commercial, and industrial buildings for various applications such as lighting, communication, security, and control systems.
Examples of ELV systems include:
Communication Systems: These systems are used to transmit and receive data, voice, and video signals. Examples of ELV communication systems include telephone systems, intercoms, and CCTV systems.
Lighting Systems: ELV lighting systems are used to provide lighting in homes, offices, and other buildings. These systems typically use LED lights and are more energy-efficient than traditional lighting systems.
Security Systems: ELV security systems include access control systems, burglar alarms, and fire alarms. These systems help to protect buildings and their occupants from security threats.
Control Systems: ELV control systems are used to control various building systems such as heating, ventilation, and air conditioning (HVAC) systems. These systems use sensors, controllers, and actuators to regulate the operation of these systems.
ELV systems are considered safer than higher voltage systems as they pose a lower risk of electric shock or fire. Additionally, these systems are often more energy-efficient and cost-effective than traditional systems, making them a popular choice in modern buildings.
