Block RKD/RTE Toroidal Isolation Transformers 40VA

Block Brand: Block

The Block RKD/RTE Toroidal Isolation Transformers 40VA act as a mains transformer for adjustment of the voltage and simple electrical isolation, while also acting as a safety isolating transformer for the safe electrical isolation of the input and output sides. These transformers may be used to set up protective separation as a protective measure in accordance with VDE 0100, and are also suitable for creating SELV and PELV circuits because of the limit on the output voltage. Additionally equipped with double voltage for series or parallel connection, along with reinforced insulation between PRI and SEC.

  • Low weight
  • Optimum Efficiency
  • Minimal no-load losses
  • Minimum size at high output
  • Very low magnetic and noise field
  • Outstanding temperature behaviour thanks to low magnetic leakage field
