  • Double output voltage for series or parallel connection
  • Very good moisture protection and low noise thanks to XtraDenseFill resin encapsulation (up to 300 VA)


Isolating Transformers

Isolating transformers with galvanic isolation provide a reliable supply to circuits with the safety measures “protective separation”. The transformers provide double or reinforced isolation between the primary and secondary sides. Any requested network configuration is possible for the secondary side, whether this involves a monitored isolated system or grounded system with fuse elements. The output voltage for the isolating transformers can be between 50 Vac and 1,000 Vac or 120 Vdc and 1,415 Vdc. BLOCK's standard range includes power outputs of up to 1 MVA.

  • Double or reinforced isolation between the primary and secondary sides
  • Flexible structure for the secondary side network configuration
  • Power output: 50 Vac to 1,000 Vac or 120 Vdc to 1,415 Vdc
  • Power output: up to 1 MVA, higher power ratings upon request


Isolating transformer for the safe electrical isolation of the input and output sides. The transformer may be used to set up protective separation as a protective measure in accordance with VDE 0100.
