DESCRIPTION OF THE SYSTEM
This unit online double conversion ensures continuous feeding in of d 'emergency lighting systems or security systems.
The double conversion system has primary to eliminate noise from the main network NL Nederlands. VFI (Voltage and Frequency
Independent): wherein the UPS output voltage is independent of the variations of the mains voltage and frequency variations are
controlled within the limits prescribed by the European Standard (IEC 110-10).
A rectifier converts the alternating current from the direct current network. This charge current batteries and activates the 'inverter.
On the basis of this current l 'inverter generates a sinusoidal alternating current which constantly feeds the loads.
Installations of lighting or security are thus powered entirely by the CPS. If there is a 'power cut, the batteries feed the' inverter.
This manual can be used for the following models:
SCB010 Series
SCB020 Series
SCB030 Series
