SIAP- SISTEMA INTEGRATO DI ALIMENTAZIONE E PROTEZIONE DEGLI IMPIANTI DI SICUREZZA E SEGNALAMENTO (RFI IS732 SPEC.) – VERSIONE TRIFASE
Uninterruptable Power System For Safety And Signalling (RFI IS732D Spec.)Three Phase Version
SIAP power systems (conforming to RFI technical specifications) are of the ON/LINE type (inverter delivering normally on the load) and are responsible for ensuring continuity of power supply to the load, with a stabilized voltage and frequency, both in the presence and absence of the grid voltage.
The Integrated System consists of the following functional branches or subassemblies:
AC Branch (Single or Redundant)
AC Branch Emergency
DC Branch.
Storage batteries
Power factor correction section
Control panel (function of sectioning off functional subassemblies and managing diagnostics)
Generator set from 15 to 550 kVA (in indoor or soundproofed outdoor version)
The ON-LINE power system assures V/F stabilized feeding voltage to the loads, under several input conditions. The unit is made up by the following sub-units:
(a) AC section No. 1 and No. 2 made up by:
rectifier
Inverter
static switch
b) Emergency AC section
