The Ruta CB central battery system is modern, reliable, and easy to operate central battery system which is constructed in accordance with the norms of VDE 108, and PN-EN 50171, 50172 standards. With the possibility to use sub-modules the system is dedicated to medium and large structures. It has been designed in SMART technology. In case of applying the addressing mode it controls each luminary. The system monitors individually each output circuit. It provides free configuration of mode both the circuit and the luminary. The driver of the system provides the possibility to program the addressing mode without any interference into the luminary without any specialized software device. . Additionally, the system has an input and SD card that allows to record and upload system settings (back-up) and the record events of the Event Log in accordance with PN-EN 50172. The records report on SD card provides possibility to print the event log register from any PC equipped with SD socket, without any extra dedicated software. Moreover, all the settings are stored in non-volatile memory and will not be lost even in case of the complete power supply cut-off. The charger provides power supplying based on Ul characteristics, with temperature compensation in accordance with PN-EN 50171. The charging is equipped with the internal active PFC module which provides obtaining high rate power factor. The linear modules are equipped with the separate AC and DC protection what significantly increases the safety level while switching on emergency lighting in the building. In DS mode the system works in IT network layout (isolated system).
