The superb quality of SIET Neon Transformer makes it fully complies with various standards and regulations (such as ENEC, IMQ,SEV, VDE, CE, UL, etc) with no need for alterations. Siet has also been qualified for International ISO 9001:2000 certificate of quality and service.   

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).

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.
