Product Description


JET Series


Portable, PRI 110 Vac, SEC 230 Vac, 250 - 1,000 VA


  • Carrying handle, mains connecting lead NEMA5-15 (USA) and socket for portable application
  • Very good moisture protection and low noise thanks to XtraDenseFill resin encapsulation
  • Very high efficiency
  • Integrated short-circuit and overload protection



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 portable application for the adjustment of the voltage in 110 Vac networks to 230 Vac equipment when no electrical isolation is required. The specified protection class is only guaranteed if a plug with at least the protection class of the device is used.
