Central Battery Systems for Emergency Lighting
CBS is a specialized power supply system designed to provide backup power specifically for emergency lighting fixtures. By maintaining a constant source of electricity, CBS systems help mitigate the risks associated with power outages, ensuring safe egress and operational continuity.
Categories of Central Power Supply Systems
The central power supply systems are divided into two main categories:
- Static Inverter Systems (AC/AC): These systems operate by providing a constant 230V AC output. They are similar to AC/DC Central Power Supply Systems but differ in that they maintain an AC output at all times.
- Central Power Supply Systems (AC/DC): During normal operation, these systems supply low voltage AC power (typically 24V, 50V, or 110V AC). However, in the event of a mains failure, they switch to providing low voltage DC power of the same voltage.
Operating Principle
The operating principle of CBS systems is quite straightforward. In the case of static inverter systems, they continuously supply AC power, ensuring that the connected luminaires receive a steady flow of electricity. On the other hand, AC/DC systems adapt by providing AC power when the mains are operational and switching to DC power when the mains fail.
Applications of CBS Systems
CBS systems are widely used in various applications, including:
- Emergency Lighting: CBS is the primary power source for emergency lighting fixtures, ensuring safe evacuation paths during power outages.
- Emergency and General Lighting: In some installations, CBS systems can support both emergency and general lighting, providing a comprehensive solution for power backup needs.
- General Lighting: In certain cases, CBS systems can also be used to power general lighting fixtures during power disruptions, enhancing building resilience.
The Central Battery System is an essential backup for lighting during emergencies. Its flexibility to provide AC or DC power makes it a versatile solution, ensuring safety and continuity in modern infrastructure.
