110/220v AUTOTRANSFORMER
Single phase
auto-transformer has fundamental, a secondary and
a standard coiling, being possible its made
with one or more taps of different tensions.
At the request, these transformers can be supply with
whole incapsuled bobbins in epoxi or with (wrapper)
mettalic protection box for te most different types
of protection (IP).
In the
are used raw materials of excellent quality acoording:
• Silicon steel sheet with their magnetic proprieties
developed through careful handling and final overboiling;
• Enamelled copper wires with reinforced isolation;
• Insulating vamish, insulator papers and electrical
ribbons specially developed for this tipe of use.
Besides the worry with the raw material, experts from
M.R. Severo search to maintain updated. Special attention
in fiven to the electro-magnetic compatibility of
their products.
The result of this work affords to the client a final
product of quality and physical and excelletn characteristics
as:
• Small waste;
• High grade of confidence;
• Slow magnetic escape;
• High efficiency;
• Excellent relation between cost and performance.
Characteristics:
| • Insulators:
paper, fibre, PVC, epoxi, fenolite, polyester; |
| •
Bichromatic hardware or synthetical enamel painting; |
| • The way out
sides, as length, colors and shapes of the cabs
are at the client´s request, and others
types of connection such as screw or sindal connector,
according the power of the transformer; |
| •
In the choices without caps there is also the
possibility of a nylon bobbin with endings for
solder or impress circuit, being possible in the
clases; |
| • Asasayed individually; |
| •
Having variations of parameters or setting, there
is necessity a previous consultation to the technical
department. |
