Autotransformers and one-phase LV and MV transformers

Characteristics :
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. 

Applications :
-    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
