Auto Transformatoren
An auto transformers is a transformer with no galvanic separation between the primary and secondary circuits.
Auto transformers for industrial use (IEC 726, NFC 52-100, NEN3184). Natural cooling, under vacuum end pressure impregnated, dielectric resistance 2000 VAC to mass, temperature class F (ambient temperature 40°C), IP20, IP23for closed construction. Other constructions on request.
Auto transformers are standard available up to 500 kVA.
For safety reasons the use of this kind of transformer is restricted for down transformation of the voltage.
