Block EL Safety Isolating Transformers 2 x 9V

Block Brand: Block

The Block EL Safety Isolating Transformers 2 x 9V are ideal for the safe electrical isolation of the input and output sides. The transformers are suitable for creating SELV and PELV circuits because of the limit on the output voltage. Well designed using safety coil bobbin in 2-chamber technology, featuring a mechanically protected winding wire feature in the coil bobbin, plus very good corrosion protection and low noise thanks to BLOCKIMPEX vacuum impregnation.

  • Solder tab for free wiring
  • Coil shell in 2-chamber technology
  • Simple mounting with robust metal footplate with oval slots
