The lighting
flux regulator "ELIGHT" series is a power
supply system for lighting installations which permits
the control and the regulation of the power rates in
lighting system. In order to optimise costs and performances
daily energy. The main advantage is an uniform level
of light, by avoiding the creation of dangerous dark
areas, caused by the lamps that are kept off, in order
to save energy. The stabilization and the regulation
of the voltage combined with the possibility to programme
the switching-up and the power reduction cycles (according
to the different installations), assure the correct
powering of every kind of light installation. The microprocessor
based control unit allows the gradual variation of the
voltage and permits a custom use of lighting systems.
The system can be programmed:
¥ directly using the keyboard;
¥ with remote management system.
It's possible to control the installation by using a
light sensor to obtain a lighting flux in relation to
day-light intensity level. For example at the entrance
or at the exit of tunnels it becomes a necessity to
regulate the level of light of the lamps according to
the outside light intensity, avoiding in that way dangerous
dazzlings. This system has a large range of applications,
it is extremely flexible an suitable both for simple
plants and sophisticated installation connected to a
remote control system.

Reducing of the management costs
Using the flux regulator, the duration of the lamps is more
than doubled.
Several tests have been conducted on different installations
and the average life of lamps is resulted to be 16/18000 hours.
We will have:
¥ Reduction of the costs for energy up to 50% thanks to the
regulation and stabilization of the voltage.
¥ Reduction of the costs for maintenance more than 50% thank
to the extended life of the lamps.
Operating cycle
Upon the power-on of the system, the regulator "ELIGHT" automatically
starts the switching up cycle to a voltage of 210V in order
to avoid the initial thermal shock on the lamps and to have
an optimum and lineal warming up of the light bulbs for a
time of 10 minutes (programmable from 0 up to 20 minutes).
Once the initial phase is completed, the regulator will power
the system at the nominal preset voltage (normally 220V).
The shift to reduced power can be programmed or can be activated
by an external control. During all day (24h) it is possible
to program 4 different phases of powering reduction all with
different voltages programmable from the 210V to 175V. In
all the phases the output voltages are always stabilized with
extreme accuracy: maximum 1,5% of the programmed voltage.
