TRANSFORMERS

Single-phase transformers

The dry type single-phase transformers has a rated power range between 10VA and 31,5 kVA. The transformers are manufactured according the IEC/EN 61558 Standards (safety, isolating, control, separating or medical transformers), IEC/EN 60076 (power transformers) or CNOMO E03.22.210N. There are different models of transformers depends of the protection index which can be IP00 or IP20, with Screw or Din rail fixing. The different size transformers work 100% of the rated power in ambient temperatures up to 40°C. There is a wide range of Transformers in stock and special transformers are designed on request.

Three-phase transformers

Three-phase power isolating transformers dry type. Intended for change of voltages with galvanic isolation, attenuation of line disturbances and/or when it is necessary to change the neutral system. Connection with terminal blocks or with screws for flats terminals. Manufactured with electrical steel with low losses and copper windings. On request we can manufacture transformers with other voltages, with taps, electrostatic screen, with thermal switch, etc. IP00 and IP23 protection index models.

AUTOTRANSFORMERS

Single-phase autotransformers

Dry type Single-phase autotransformers with rated power range between 100 VA and 10 kVA. They are intended for use as voltage adapter when an economical solution is required in applications where the galvanic isolation is not required. Manufactured according IEC/EN 61558 or IEC/EN 60076 standards. Sized to work with 100% of rated power in ambient temperatures up to 40°C. Range of standard types in stock and customer design on request.

Three-phase autotransformers

Dry type Three-phase autotransformers with rated power range between 500 VA and 200 kVA. They are intended for use as voltage adapter when an economical solution is required in applications where the galvanic isolation is not required. Manufactured according IEC/EN 61558 or IEC/EN 60076 standards. Models with IP00 protection index or with metallic case with IP23 protection index (available wheels kit). Sized to work with 100% of rated power in ambient temperatures up to 40°C. Range of standard types in stock and customer design on request.

REACTORS

Single-phase reactors

Single-phase line reactors (intended for the attenuation of notches and spikes, reduction of harmonics and limitation of inrush currents in power converters and motor drives), as well as DC link chokes for DC side of converters. Manufactured with magnetic steel with low losses and copper windings. On request we can manufacture reactors with other characteristics, for other applications or with thermal switch. 

Three-phase reactors

Three-phase line or motor reactors for power converters (intended for the attenuation of notches and spikes as well as reduction of harmonics and limitation of inrush currents in power converters and motor drives). There are also types for the protection of capacitor banks in power factor correction equipment with presence of harmonics (to avoid resonance effects, to minimize harmonic currents through the capacitors and to reduce losses, increasing capacitor life. Manufactured with electrical steel with low losses and copper windings. On request we can manufacture reactors with other characteristics, with built-in thermal switch, etc.
