Product Description


AIM Series


PRI 115/220/230/240 Vac, SEC 115/220/230/240 Vac, 0.8 - 16 A


  • Screw terminals under cover with strain relief
  • Very good moisture protection and low noise thanks to XtraDenseFill resin encapsulation (AIM 1.8/8 - AIM 5.0/2.5)
  • Very high efficiency
  • Integrated short-circuit and overload protection
  • Low weight and small size (compared to isolating transformers)



Autotransformers are the efficient and ideal solution for minor voltage adjustments. Compact designs can be provided depending on the voltage difference. Autotransformers feature lower losses compared with isolating transformers with the same power rating. The transformers without galvanic isolation also feature inverse operation. BLOCK's standard range features power outputs of between 150 VA and 250,000 VA

  • Efficient solution for minor voltage adjustments
  • Inverse operation possible
  • Power output: 250 VA to 250,000 VA


Autotransformer for adjustment of the voltage on the input and output sides with no requirement for electrical isolation.
