Autotransformer
VT 100-EN
Characteristics
General data
The autotransformers of the VT-EN series are used for voltage adjustment without the need for galvanic isolation. The transformers feature lower weight and a smaller form factor compared to other transformer types with separate windings and can be easily mounted using robust metal base brackets with elongated holes.
Benefits
› Autotransformer according to EN (IEC) 61558-2-13
› Very high efficiency
› Excellent moisture protection and low noise emission thanks to BLOCK IMPEX vacuum impregnation
› Touch-protected connection terminals according to UVV BGV A3
