Power transformers (ferrite, inductor, three-phase)

Italtras designs and manufactures their transformers in compliance with the European standards issued by CENELEC and in conformity with the Low-voltage EEC-Directive LV73/23/EEC and 93/68/EEC. Some of our models are also ENEC (IMQ)-certified for compliance with these rules. The toroidal transformers, respect, also, the UL506 Americans standard and have branded cURus (UL+ CSA).

The cure, seriousness and technological research that we infuse in our work guarantees that our products are of superior quality. The same type of care goes into the relationship we have with our clients, which is founded on the philosophy of maximum satisfaction. These are the objectives of our work: which today and everyday we do with a lot of passion.

All our EI-laminated-core transformers have been assigned with ENEC type-approval.

Power toroidal transformers cURus (UL+CSA)
Set of main power transformers, designed and built in conformity with the international standards EN61558 and UL 506. The toroidal-core transformers offer important advantages over the traditional laminated-core transformers. The transformer capacity being equal, these types of transformer offer: lower weight, reduced overall dimensions, lowest flow leakage, lower consumption under no-load conditions

TECHNICAL FEATURES:
Primary: From 100-240Vac 50/60Hz
Secondary: from 5V to 240V from 30 to 750VA
depending on the product model
Tolerance limits: secondary Voltage +/-1%
Insulation: 5 Mohms, 500Vdc
Insulation voltage: 4Kv - 1 minute
Materials: Class B, 130 °C
ta: 40 °C
Terminals: tinned outgoing wires

Power transformers and inductors for electronic applications
Several ferrite types are used for the core of our transformers; in particular the following types are available:
EE: this is the most frequently used and less expensive type of ferrite. Its name proceeds from the shape of the two half-cores.
Applications: Suppressor transformers, Small signal transformers
ETD (Economic Transformer Design): its main characteristic consists of an almost even cross section offered to the magnetic flow. Optimum volume/weight/performance ratio. Applications: Switching power supply transformers.
EFD (Economic Flat Transformer Design): with flat core. This type of ferrite is mostly applied to extremely compact transformers. Applications: Switching power supply transformers.
RM (Rectangular Modular): owing to their square shape, particularly suitable for applications with high density of components, where the requirement is for as smallest overall dimensions as possible. For instance, RM6 means that coil and core take up a square surface corresponding to 6x6 modules (1 module = 2.54 sq.mm surface). Applications: Inductances, Suppressor transformers, Small signal wide-band transformers.
Set of linear and toroidal coils, manufactured according to the customer's specification.
Suitable for vertical or lengthwise assembly, on request.

Depending on the core kind of material, coils may be suitable to different applications; some examples are listed below:
Toroidal-core Suppressor inductances; To clear the commoning noise: two separate windings with core connected to the loop conductors. These push-pull windings generate opposite magnetic flows with consequent low current load impedance and high noise signal impedance.
Straight-core (rod) -small non-adjustable inductors; -choke coils for high frequency radio and TV sets.

Power transformers Three-Phase
Set of main power transformers, designed and built in conformity with the international standards EN61558. Specially developed for three Phase applications.

TECHNICAL FEATURES:
- Insulating class B
- Frequency. 50/60 Hz
- Open execution. Protection index IP00
- Max ambient temperature 40°C
- Frame with earth connection on request
- Impregnated in vernish and tropicalised
- On request can be supplied other vector groups.

Adapters for power supplies
The AC/AC and AC/DC adapters of this series consist of one main plug casing made of HT ABS, housing a power transformer and an output cable suitable for fitting with a connector, according to the customer’s specification requirements. Two versions are available, respectively one with plug-in casing for power rating ranging from 3 to 9 VA, and another one for bench mounting, with power ratings from 13 to 20 VA.
