The Block ECO Efficient PCB Mount Transformer 5VA, 2 x 9V, 2 x 277mA acts as a safety transformer for the safe electrical isolation of the input and output sides. The transformer is suitable for creating SELV and PELV circuits because of the limit on the output voltage.

Designed with low no-load losses (max. 0.6W), as well as being unconditionally short-circuit proof (up to 1.5 VA), this transformer also has double output voltage for series or parallel connection, while boasting permanent corrosion protection, high insulation value and maximum electrical reliability thanks to XtraDensiFill resin encapsulation.


  • Designed for high ambient temperatures
  • Minimum size at high output
  • Coil shell in 2-chamber technology
  • Self-extinguishing potting material
  • Vacuum casting resin rugged stain (self-extinguishing, UL 94 V-O listings)
