Central Battery Control Unit CCU 24V Series
Central Battery Systems CCU 24V Series is a central emergency lighting control unit for a 24VDC system, designed to supply power to emergency lighting lamps when the main power fails. The system automatically controls lamp operation to ensure continuous illumination, helping improve evacuation safety inside buildings.
The unit is equipped with a Sealed Lead-Acid Maintenance Free (SLA) battery, together with a 3-Step Charger System and a built-in monitoring system for both voltage and battery status, enhancing safety and extending the service life of the system.
In addition, the CCU 24V Series comes with Auto Test and Remote Test functions for convenient inspection and maintenance, reducing the burden of regular maintenance and increasing operational reliability. The enclosure is made of electro-galvanized steel coated with epoxy powder coating, providing strength and corrosion resistance. It is suitable for indoor installation and professional-grade emergency lighting systems.
