With
it's strong steel container of electro-galvanised plate, coated
with thermosetting polyester powders, the whole transformer
is surrounded by a shield at zero potential that is higly resistant
to atmospheric conditions, and is prevented from splitting and
thermal dilatation (known to cause cracks). The transformer
is built around a patented magnetic core of special low-leakage
ferromagnetic alloy, which limits heat loss, resulting in a
much lower input current in the absence of load.
The two
independant secondary windings are earthed by means of a fault
detector. Impregnation with epoxy resin plus treated mineral
excipient fillers is carried out under hard vacuum and a controlled
atmosphere and ensures excellent heat conductivity and dielectric
characteristics.
There are
still many special features and all these make the Siet Transformer
a class above all the other transformers. Due to these uncommon
characteristics it has penetrated even the most difficult markets
in the most varied of climates.
Special Transformer up to 200kV (information available upon request). |

COIL
& CORE TRANSFORMER, OFFERS NOT ONLY THE SAME RELIABILITY
AND DURABILITY BUT ALSO ELECTRONIC COMPATNESS. |

We
challenged the technical limits in the development of a very
small size coil and core transformer in the weight of 1.8kg
only for cold cathode and neon signs. Ideal for narrow space,
small channel letters, cove lighting and false ceilings, with
the proven of its reliability and durabily, least interference
with metal objects because of its low frequency current, enabling
your lamps to run 24/7 (within specification).

Where
atmospheric agents are less aggressive, the same transformer
has been put in a strong, self-extinguishing plastic container
suitable for indoor applications, with reduced height and light
colour housing.
Like
the Metalbox, it is impregnated with special resin, the steel
screws are treated with Dacromet, the wire-clamping plates are
in nickel-plated brass.

LEXADISTOP
is the
same as LEXABOX
but built-in with the earth leakage switch (Distop). |

This
device (Dimmer) allows a brightness variability
through the control of the neon transformer supply tension from
0 to 100%; it can be connected to more than one transformer at
a time through the STAR connection boxes until the maximum capacity
allowed by the value indicated in the plate.
The dimmeration
can be obtained in different ways, depending on the preferences:
1.) Manually, through a remote control in a wall embedded box.
2.) Through a twilight photocell that can work also as a save
energy for the electrical consume reduction
3.) Programmable through PLC system: intensity variations are
programmed at will.
This system
is a valid answer to the problem of luminous pollution because
it allows an energetic saving through programming a light intensity
reduction at fixed times.
