Autotransformers and three-phase, three-one, two-phase LV, MV or HVA transformers

Power: 1 VA up to 20 kVA (depending on the frequency of use)
Frequencies: 50 to 1 kHz
Voltages: 1 V to 10 kV

Fields of use:
- Transmission of electricity from a one-phase network;
- Measure of an electrical parameter (current, voltage);
- Obtaining a quality-price ratio;
- Obtaining a simple and effective industrial profile;
- Obtaining an easily convertible product.

- Distribution cabinet from a one-phase network, with or without galvanic isolation;
- Independent transformation post, covered or not, according to a IP00, IP21, IP23, IP54, IP55 or IP65;
- Voltage stabilizer of ±1 or 2% from a highly variable network in amplitude (± 20%);
- Ferroresonant;
- Transformation post conditions comparable to ATEX;
- Extension of very low voltage, high current energy.

These values are given as an example and are not exhaustive for particular solutions.
