  • Low leakage current and high insulation resistance

Prose

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

Applications

Isolating transformer for mobile use to minimize mains supply faults such as disturbing pulses and electrical noise. The specified protection class is only guaranteed if a plug with at least the protection class of the device is used.
