Single Phase Autotransformers


Standard C.E.I. 14/8 issue 1162 IEC 726
ATM series autotransformers have an identical magnetic structure to that of normal transformers. Instead of having the 2 winding H.V. and L.V. realised in two distinct spiral the L.V. winding represent a portion of the entire H.V. winding.

On request the dimensions can be varied according to available space.

 Series production:
- Primary voltage 0/230/400V
- Secondary main voltage 110-125-160-230-270-400V;
- Insulation class: E
- Protection: IP00;
- Frequency: 50/60 Hz
- Open execution
- Electrical protection class I
- Impregnation with resin
- Tropicalised
- Full data always refer to the max secondary voltage
Necessary data for quotation request or order:
a) power in V.A.
b) voltage and frequency of supply line;
c) secondary voltage
d) ambient temperature
e) working ambience.
