Fire redundant RPS 80A LE-Ra-SBC-24 power supply (EN54-4)  has been certified by SV Sistemi di Sicurezza and integrated into EXFIRE360 panel, with RS485 serial port for centralization of information on current and settings, readings with RPS characteristics (redundant power supply), capable of handling high energy capacity 80A, provided with external battery packs with capacity of up to 700Ah. The system provides a voltage proportional to the final charge voltage ( 27.6 Vdc @ 20C), with a power configuration in N 1 redundancy through 2 pull-out drawer units placed on a mechanical rack 19 1U called FPS- S/1U, or different configurations type N 2 (1 Rack FPS S/1U complete with 3 feeders FPS1000-24), or a configuration N M 1 (including 2 rack FPS S/1U in parallel, with each 2 FPS1000-24) that can be implemented in the event of AC different power sources .

Certified EN54-4 power supply  with redundant RPS 80A includes groups of batteries of mixed series / parallel external (standard batteries lead-calcium hermetic type VRLA FIAMM or traditional vessels fillable) that, with AC electrical power, are kept in charge thanks to the control system; through the reading of the internal current branch battery, it modulates the output voltage of the / racks to maintain the charge profile as explained below.

The batteries are sealed lead-acid type without refilling. The part of the power will be made in accordance with the current applicable legislation and it will be reported and reduced all the possible points of contact with the power supply. The power supply will be carried out in accordance with EN 54-4 A1. EN54-4 certified redundant 80A RPS power supply and it will be able to provide information to the control unit reporting fault and malfunctioning conditions.

It can stop the primary network (upstream) to test the service in secondary power supply. The charger / power supply will be dimensioned to work 72 hours in the absence of network power. The lack of primary power will be reported. The anomaly of disconnected batteries will be indicated on the control panel.
